After the battle of Hastings, William the Conqueror marched upon London, but was opposed by a body of the citizens in Southwark, whom he repulsed; but recognising their valour and perceiving the strength of the City's fortifications, he went to subdue the Western Counties, and his success in that direction showed the Londoners that the wisest and most politic course would be to submit; when the Norman duke entered the City, and was presented with the keys and acknowledged as King of England. He was no sooner in possession of the City than he caused three castles to be erected, ostensibly for the protection of the City, but really to overawe the inhabitants. These were the Tower at the eastern, and Baynard and Montfichet Castles at the western, extremity of the walls. The Tower became the residence of the Norman kings, and Baynard Castle that of the chatelain and standard-bearer of the City—offices held first by the Baynards, and afterwards by the Barons Fitzwalter. Montfichet Castle was destroyed by fire in the reign of William, and the Black Friars' Monastery built on the site—the best of the stones being used in the re-edification of St. Paul's Cathedral, which had been destroyed by fire.
Fitzstephen speaks of the walls being "both high and thick, with seven double gates," which appear then to have been in good condition, although the south wall had been "subverted and carried away by the tide." But very soon after some portions seem to have fallen into a ruinous condition; as Roger of Wendover and Matthew Paris tell us that the barons, when in arms against King John, in 1215, entered the City by Ealdgate, and demolished the houses of the Jews, to obtain materials wherewith to repair that gate and the adjoining walls. In 1257, also, it is stated, Henry III. "caused the walls, which were greatly decayed, and destitute of towers and turrets, to be repaired in a handsomer manner than before, at the common charge of the City."
King Edward I. granted permission to Kilwarby, Archbishop of Canterbury, to take down the wall, from Ludgate to the Thames, for the purpose of enlarging the Church of the Black Friars, and in 1282 granted a murage charter to the Corporation for levying certain tolls throughout the kingdom, for making a new wall from Ludgate—westward to Fleet Bridge, along behind the houses and by the water of the Fleet to the Thames, "from the aforesaid day to the end of three years next following," from which none were exempt, saving the city of Winchester, and a few other cities, which, by composition, were to pay no Portage, Murage, or Pannage. After an enumeration of the articles to be subjected to toll, amongst which are: "Riges, Cetewal, Kanel, Frankincense, Cummin, Liquorish, Zuber, Cyromontani, Frails of Figs," etc., is added, "Whereas we have granted you for aid of the work of the walls of our City and the closure of the same, divers customs of vendible things, coming to the said City, to be taken for a certain time, we command you that you cause to be finished the wall of the said City now begun near the Friars-preachers, and a certain good and comely tower at the head of the said wall within the water of the Thames," etc. Similar letters were issued by Edward II. in the first, second, sixth, eighth, and twelfth years of his reign; but as it was found that levying a toll on retail commodities caused an insufficient supply, the patent ran in the latter year, that—"Victualia non adducuntur, in detrimentum civitatis;" but that impositions should be levied in bulk on all merchandise brought by land or water. Richard II., in a letter to the Corporation, said in the preamble: "Know ye, that whereas the walls and forts of the City be old and weak, and for want of repair are fallen down in some places, as also the ditches of the said City are exceeding filled with dirt, dunghills, and other filth, not only to the evident danger of the said City and inhabitants thereof, but also to the manifest disgrace and scandal of the whole City," etc.; and granted to the Mayor and Corporation power to levy tolls for ten years for the purpose of placing the wall in a state of thorough repair. In order to enforce these murage tolls it was customary to have chains fixed across the entrances to the City, and no country people with provisions for sale were allowed to pass until they had paid the dues.
In the reign of Edward IV., Ralph Joscelyne, the mayor, repaired the wall from Aldgate to Aldersgate, for which purpose he caused bricks to be made in Moorfields, where also the lime brought from Kent was burnt for that purpose. This was in the year 1477, and several of the City companies—the Drapers (of which company the mayor was a member), the Skinners, the Goldsmiths, and others—contributed to the work, and placed their arms on the portions they executed. The executors of Sir John Crosby also contributed freely out of the funds they held in trust towards the same object. By an order of the Common Council each parishioner also was directed to pay sixpence every Sunday at his Parish Church until the work was completed. After this the walls were neglected and suffered to fall in ruin. Camden, writing in 1607, says that the north wall "having been repaired by one Joscelin, who was mayor, it put on, as it were, a new face and freshness, but that towards the east and west, though the barons repaired it in their wars of the demolished houses of the Jews, is all ruinous and going to decay. For the Londoners, like the Lacedæmonians of old, do slight fenced cities, as fit for nothing but women to live in, and look upon their own City to be safe, not by the assistance of stones, but by the courage of its inhabitants." Nevertheless when the Civil Wars between Charles I. and his Parliament had fairly commenced, the citizens bethought them of their walls and forts as no contemptible means of defence. London had declared most decisively for the Parliament; and in 1643, the Common Council gave directions that the ditches should be cleaned out of the accumulations of rubbish, all outside buildings cleared away, the bulwarks put in repair and mounted with cannon, and new works added to the weaker parts of the walls. The Parliament confirmed this resolution, and extended a plan of fortification, so as to include Southwark and Westminster. A chain of forts surrounding the whole, and lines of communication, were ordered to be erected. All the entrances to the City were closed excepting those at Charing Cross, St. Giles-in-the-Fields, St. John's Street, Shoreditch, and Whitechapel; and these were fortified with musket proof breastworks. To carry out these extensive works a levy was made of eight-fifteenths on all the wards of the City, which was cheerfully assented to by the citizens, and the works were commenced without delay, and carried on with such zeal and alacrity that the whole was completed in an incredibly short space of time. In the year 1647, when the dispute was raging between the Presbyterians and the Independents, the city was divided in opinion: but when the army under Fairfax advanced from Hounslow upon London, the Mayor and Corporation met and saluted the general at Charing Cross; and by an ordnance of Parliament he was constituted Constable of the Tower, the army thus becoming masters of the City. The Parliament then demanded a loan of £50,000 from the City, which was not complied with and in consequence an Act was passed for demolishing the fortifications of London, Westminster, and Southwark.
Whether the Roman wall was protected by a ditch does not appear; probably not, as the first mention we have of one being made is by Dunthorn, who informs us that William, Bishop of Ely, Regent of England when Richard I. was absent in Palestine, made a ditch round the Tower as a defence against John, the King's brother, soon after which the citizens dug a ditch round the walls generally, which they commenced about 1190, but left it unfinished until 1213, as the register of Barmondsey states, when it was recommenced, and completed in two years. This ditch was 200 feet broad, but was afterwards neglected, and gardens planted and houses built upon it. In 1354, Edward III. caused it to be cleansed; and again in 1379, by direction of Lord Mayor Philpot, as also by Lord Mayor Fawconer, in 1414, and Lord Mayor Joceline, in 1477. In 1519, 10th Henry VIII., it was "cleansed and scowered" between Aldgate and the Tower—the chief ditcher being paid 7d. per day, the second ditcher 6d., other ditchers 5d., and every "vagabond" (labourer) one penny and meat and drink at the charge of the City. It was cleansed out again in 1549 at the expense of the trade guilds, and twenty years after, temp. Elizabeth, at a cost of £814 15s. 8d., at which time "it had therein great store of good fish of divers sorts." After this the expense was defrayed by letting the banks and "the whole spoil of the ditch," excepting in 1595, when the Common Council granted two-fifteens for the purpose. In the following century the ditch was filled up, excepting Fleet Ditch on the west, which, after the Fire of 1666, was, by direction of the Mayor and Court of Aldermen, ordered to be cleansed, enlarged, and made navigable for barges up to Holborn-bridge. The sides were built of freestone, and it was arranged that its banks should be lined with warehouses and wharves, but this part of the project was not carried out in its integrity. "This ditch was built and made by Sir Thomas Fitch, bricklayer, who contracted with the City for a very considerable sum, and enriched himself thereby." In 1723 the Corporation obtained an Act of Parliament for filling up the channel from Fleet-bridge to Holborn-bridge, which had become choked with mud and was no longer navigable, and to build thereon a new market in place of Stocks Market, near the Exchange, which it was proposed to dismarket and demolish, and erect on the site a Mansion House for the Lord Mayor.
We have seen that in the old Roman walls there were four gates, the exits of four roads radiating from the "milliarum," now called London Stone. These gates were—Aldgate on the east, Aldersgate on the north, Ludgate on the west, and Dowgate on the south. What were the architectural features of these gates we know not, but undoubtedly they were similar to the usual Roman gateways, with round-arched openings and fortified upper chambers for the purpose of defence.
Aldgate, or Ealdgate, so called by the Saxons on account of its antiquity, was placed by King Eadger in the hands of the knights of the Knighten Guild, who held the soke, now called Potsoken Ward Without, by charter. Afterwards it became part of the demesne of Maud, queen of Henry I., who bestowed it upon the prior and canons of her foundation, the Priory of the Holy Trinity, along with the soke and franchise of the ward. In 1215, the barons, in their war with King John, being favoured by the Londoners, entered the City by Aldgate, which was in a ruinous condition, and repaired, or rather rebuilt it, in the Norman style, with an arched opening built from the ruins of the Jews' houses, and bulwarks of Caen stone. In the 11th Edward IV., the Bastard of Fauconbridge sailed up the Thames with his fleet, he being the admiral, to attack London in the then hopeless interest of the Lancastrian ex-king, when the Londoners hastily fortified the river front, and he landed in Essex, marched to Aldgate, and forced an entrance; but the portcullis having been lowered, separated his forces, and they were defeated and driven back to Mile-end, many being slain and others dispersed. Having fallen to decay, the gate was taken down in 1606, and rebuilt, the finishing stone having been laid in 1609. It consisted of two three-storied square flanking towers, with a deep recessed centre, containing the archway and a room above, and a footway postern in one of the towers. It was ornamented with two stone medallions, copies of two Roman coins found on digging the foundations, a figure of King James I., in gilt armour, over the arch, figures of two soldiers on the battlements, and a representation of Fortune standing on a globe. The rooms over the gate were appropriated to the Lord Mayor's carver as a residence.
Aldersgate, like Aldgate, was denominated Eldergate by the Saxons on account of its antiquity. It was at divers times enlarged, with additional buildings, and was rebuilt in 1617 by direction of the Corporation, William Parker, merchant tailor, contributing £1,000 towards that object. It was built with a recessed centre, and square flanking towers four stories in height. Over the arch was an equestrian figure of King James I., who entered London by this gate when he came from Scotland to succeed Elizabeth on the throne of England, and on the opposite or southern front were statues of the prophets Jeremiah and Samuel, and another representation of King James, seated in a chair of State, in his royal robes. The rooms over the postern were occupied by the Common Crier of the City. This gate suffered great damage in the Fire of 1666, but was restored at the charge of the City, during the mayoralty of Sir Samuel Stirling.
Ludgate, Geoffry of Monmouth informs us, was built by King Lud, circa A.D. 66. It was repaired and partly reconstructed by the barons, in 1215, out of the materials of the Jews' houses, and was again rebuilt in 1586, when a stone was found in the old structure bearing an inscription in Hebrew characters, "This is the station of Rabbi Moses, the son of the honourable Rabbi Isaac." During some repairs in 1260, statues of Lud, and other ancient kings, were placed upon the gate; "but," as Stow says, "these had their heads smitten off in the reign of Edward the Sixth, by unadvised persons and such who judged every image to be an idol. In the reign of Queen Mary, they were again repaired, and had new heads set to their old bodies." In 1586, being much decayed, it was entirely rebuilt by the Corporation, at a cost of £1,500, with statues of Lud and other kings on the east, and of Queen Elizabeth on the west. From the year 1378, this gate was used as a prison for freemen of the City guilty of the crimes of "debt, trespasser, accompts and contempts." It was consumed in the Fire of 1666, but substantially rebuilt, like an ordinary house, with central archway and side portions, and ornamented with statues of Queen Elizabeth, King Lud, etc.
The fourth ancient gate was the exit to the ferry across the Thames, called Dowgate, Downgate, or Dourgate, the great road to the Kentish sea-coast, running from the opposite bank. It seems to have disappeared, along with the ferry, when the bridge was built and the gateway transferred to that locality.
