The Electoral palace, which opens, on one side, to the city, and, on the other, to the ramparts, was built by the Elector Charles-Philippe, who, in the year 1721, removed his residence hither from Heidelberg, on account of some difference with the magistrates, or, as is said, of the prevalence of religious disputes in that city. He began to erect it in 1720; but the edifice was not completed, till the right wing was added by the present Elector, not to be used as a residence, but to contain a gallery of paintings, cabinets of antiquities and natural history, a library, treasury and manege. We passed a morning in viewing the apartments in the other wing, all the paintings and books having been removed from this, as well as great part of the furniture from the whole palace, in the dread of an approaching bombardment. The person, who shewed them, took care to keep the credit of each room safe, by assuring us at the door, that it was not in its usual condition. The Elector had been, for some months, at Munich, but the Duke and Duchess of Deux Ponts and their family have resided in this palace, since their retirement from Deux Ponts, in the latter end of the campaign of 1792.

The rooms are all lofty, and floored with inlaid work of oak and chesnut; the ceilings, for the most part, painted; and the walls covered with tapestry, finely wrought, both as to colour and design. Some of this came from a manufactory, established by the Elector, at Franckenthal.

The furniture, left in several of the rooms, was grand and antient, but could never have been so costly as those, who have seen the mansions of wealthy individuals in England, would expect to find in a palace. The Elector's state-bed was inclosed not only by a railing, but by a glass case to the height of the ceiling, with windows, that could be opened at pleasure, to permit a conversation with his courtiers, when compliments were paid literally at a levee. In the court of France, this practice continued even to very late years, and there were three distinct privileges of entrée, denoting the time, at which persons of different classes were permitted to enter the chamber. In the Earl of Portland's embassy for King William to Louis the Fourteenth, it was thought a signal mark of honour, that he was admitted to his audience, not only in the chamber, but within the rails; and there the French Monarch stood with the three young Princes, his grandsons, the Count de Tholouse, the Duke d'Aumont and the Mareschal de Noailles. The Duke made his speech covered, after which the King entered into conversation with him, for several minutes.

One room, at Manheim, was called the Silver Chamber, from the quantity of solid silver, used about the furniture. Such articles as could be carried away entire, had been removed, but the walls were disfigured by the loss of the ornaments torn from them, on account of their value. In several rooms, the furniture, that remained, was partly packed, to be carried away upon the next alarm. The contents of the wardrobe were in this state, and the interior of these now desolated apartments seemed like the skeleton of grandeur. The beauty of the painted ceilings, however, the richness of the various prospects, commanded by the windows, and the great extent of the building sufficiently accounted for the reputation, which this palace has, of being the finest in Germany.

It is built of stone, which has somewhat the reddish hue of that used at Mentz, and, though several parts are positively disapproved by persons of skill in architecture, the whole is certainly a grand and sumptuous building.

The situation of Manheim and the scenery around it are viewed to great advantage from the tower of the Observatory, in which strangers are politely received by the Professor of Astronomy, whose residence is established in it. From this are seen the fruitful plains of the Palatinate, spreading, on all sides, to bold mountains, of which those of Lorrain, that extend on the west, lose in distance the variety of their colouring, and, assuming a blue tint, retain only the dignity of their form. Among these, the vast and round headland, called the Tonnesberg, which is in sight, during the greatest part of the journey from Mentz to Manheim, is pre-eminent.

But the chain, that binds the horizon on the east, and is known by the name of the Bergstrasse, or road of mountains, is near enough to display all their wild irregularity of shape, the forest glens, to which they open, and the various tints of rock and soil, of red and purple, that mingle with the corn and wood on their lower steeps. These mountains are seen in the north from their commencement near Franckfort, and this line is never interrupted from thence southward into Switzerland. The rivals to them, on the south west, are the mountains of Alsace, which extend in long perspective, and at a distance appear to unite with those of the Bergstrasse. Among the numerous towns and villages that throng the Palatinate, the spires of Oppenheim and Worms are distinctly visible to the north; almost beneath the eye are those of Franckenthal, and Oggersheim, and to the southward Spires shews its many towers.

In the nearer scene the Neckar, after tumbling from among the forests of the Bergstrasse, falls into the Rhine, a little below the walls of Manheim; and the gardens of a summer chateau belonging to the Elector occupy the angle between the two rivers.

These gardens were now surrendered by the Prince to be the camp of three thousand of his troops, detached from the garrison of the city, which, at this time, consisted of nearly ten thousand men. In several places, on the banks of the two rivers, batteries were thrown up, and, near the camp, a regular fort, for the purpose of commanding both; so that Manheim, by its natural and artificial means of defence, was supposed to be rendered nearly unassailable, on two sides. On that of Heidelberg, it was not so secure; nor could the others be defended by a garrison of less than 15,000 men. It was on this account, that the Elector detained ten thousand of his troops from actual service, contrary, as is said, to the remonstrances of the Emperor, who offered, but without success, to garrison his capital with Austrians. From the observatory, the camp and the works were easily seen, and, by the help of a Dollond telescope, the only optical instrument remaining, the order of both was so exactly pointed out by our guide, that it was not difficult to comprehend the uses of them. Military preparations, indeed, occurred very frequently in Manheim. In the gardens of the chief Electoral palace, extending to the ramparts over the Rhine, cannon were planted, which were as regularly guarded by sentinels as in the other parts of the fortifications.

All the gates of Manheim appear to be defended by fortifications of unusual strength. Besides two broad ditches, there are batteries, which play directly upon the bridges, and might destroy them in a few minutes. The gates are guarded, with the utmost strictness, and no person is suffered to enter them, after ten at night, without the express permission of the governor. When a courier arrives, who wishes to use his privilege of passing, at all hours, he puts some token of his office into a small tin box, which is kept on the outside of the ditch, to be drawn across it by a cord, that runs upon a roller on each bank. The officer of the guard carries this to the governor, and obtains the keys; but so much time is passed in this sort of application, that couriers, when the nights are short, usually wait the opening of the gates, which is soon after day-light, in summer, and at six, or seven, in winter.
