The character of the Roman remains dug up from time to time within these walls shows that it was formerly a place of great resort. Under the protection of this citadel, and later under the protection of the Pax Romana, villas were built up outside the walls for the residence of the better sort. All round the walls also sepulchral remains have been discovered; they were afterwards included in the larger wall of the city which was built towards the close of the fourth century.

London was then, and for many years afterwards, divided into London east and west of the Walbrook. On the western side was the quarter of the poorer sort; they had cottages on the foreshore—as yet there was no wall. The better class lived outside the fort, along the eastern side of Walbrook, and in Cornhill, Threadneedle Street, and Bishopsgate Street. Down below were the three Roman ports, afterwards called Billingsgate, Dowgate, and Queenhithe. Walking down Thames Street one finds here and there an old dock which looks as if it had been there from time immemorial.

I have sometimes been tempted, when in Thames Street—that treasure-house of memories, survivals, and suggestions—to think that these narrow lanes sloping to the river are of Roman origin, left when all the rest was wrecked and lost, and that they are still of the same breadth as they were in the fourth century. This, however, is not the case. I shall show presently the origin and meaning of these narrow streets running up the hill from the river into Thames Street: they are all, in fact, connections of the quays on the foreshore with the merchants’ warehouses in Thames Street. Along the better streets, on the north of Thames Street, the traders put up their stalls and kept their shops; the stalls were at first mere temporary sheds resting against the walls of villas. These villas belonged, not to the millionaire Lucullus, for whose palace the whole world could be ransacked, but to the well-to-do merchant, whose taste was not much cultivated. He called in the best artist of the city. “Build me a villa,” he said, “as good as my neighbour’s. Let there be a fine mosaic pavement; let there be fountains; let there be paintings on the walls, lovely paintings—nymphs and fauns, nymphs bathing, plenty of nymphs, dancing girls, plenty of dancing girls; paint me Hercules drunk, Loves flying and playing tricks, warriors with shields, sea pieces, ships; paint me my own ships sailing. And take care of the hypocaust and the warming pipes, and see that the kitchen is suitably furnished.”

The earliest, the natural port of London was the mouth of the Walbrook, called afterwards Dowgate.

In the western wall of the Roman citadel was the gate which served at once for the road or street across the City to Newgate, and for that part of the trade which belonged to the citadel. The Walbrook at this time was a considerable stream. It was partly a tidal stream, but it was fed from above by many tributaries on the moorland. Here the ships first began to load and to unload. For their convenience quays were constructed on piles driven into the mud and shingle of the foreshore. As the trade increased, the piles were pushed out farther and the quays were broadened.

When trade increased and the difficulties of getting through the bridge were felt, another port was necessary. It was perfectly easy to construct one by cutting it out of the soft foreshore and then banking it up with strong piles of timber. Piles and beams were also driven in on either side for the support of quays, which could thus be extended indefinitely. The place chosen was what is now called Billingsgate. It was close to the bridge and the bridge gate; so that while goods could be landed here for the trade of the City—whence they could be easily distributed throughout the north and midland of the island,—communication was established with the south by means of the bridge (see Appendices I. and II.).

Later on, but one knows not when, the port of Queen Hythe, formerly Edred’s Hythe, was similarly constructed. I am inclined to believe also that Puddle Dock represents another ancient port; but whether Roman or Saxon, it is now impossible to decide.

The poorer part of the City was that part lying between Puddle Dock and Dowgate: we do not find tessellated pavements here, nor remains of great buildings. The houses which stood upon the pavements were modest compared with the villas of the Roman millionaire; but they were splendid compared with other houses of the City.

For the convenience of the better sort there was the bath, in which everybody spent a part of the day; for the merchants there were the quays; there was the theatre; and there was the amphitheatre. It is true that no trace has ever been found of theatre or of amphitheatre; but it is also true that until recently no trace was found of the Roman citadel, and, as I have said, no trace has ever been found of forum or of temples. We will return to this subject later.

To one standing at the south end of the narrow wooden bridge across the Thames, Augusta, even before the building of the wall, appears a busy and important place. Exactly opposite the bridge, on a low eminence, was a wall, strong though low, and provided with rounded bastions. Above the wall were seen the columns of the forum and of two temples, the roofs of the great hall of justice and of the official offices and residences.
