The _Champ de Mars_ was formed into a grand amphitheatre, having at one end the military school, against which was erected a covered gallery two hundred and twenty-eight feet (French measure) in length, and twenty-one in heighth, for the king, queen, foreign ambassadors, national assembly, &c. &c. and at the other the triumphal arch; from which, to the military school, on either side were thirty rows of seats raised one above another, two thousand seven hundred and ninety French feet in length. In the middle of the area was an altar in a circular form, whose circumference was six hundred and forty-eight feet, French measure, and whose heighth was twenty feet, built of stone taken from the Bastille. The rest of the area, except the places for the federation, was filled with seats; the whole forming an oblong, capable of accommodating between four and five hundred thousand people. Out of these limits were a number of galleries, erected for a great multitude of spectators. Opposite the triumphal arch, a bridge of boats was thrown across the Seine, and the banks of the river was lined with cannon.
For a great distance round the _Champ de Mars_, a number of temporary buildings were erected for the entertainment of the people.
When we had surveyed these admirable works, we went to the royal palace, which was built by cardinal Richelieu, and given by him to Lewis the XIV. but is now the town seat of the duke of Orleans, who is a nobleman of royal blood, and enjoys the greatest revenue in France. This palace is a most elegant and magnificent structure, which is adorned and beautified with splendid ornaments, that dazzle the eyes of a spectator. In the centre of this structure is an oblong square, laid out in beautiful walks, interspersed with trees, flowers, &c.
Sometimes the duke resides in one part of the palace himself. But the other part is let out in shops, which are under piazzas, and the rooms over them to gay fashionable ladies and gentlemen.
In this palace there is a gallery, which contains most of the illustrious personages that France has produced, drawn by the greatest masters: Italy has been ransacked, and no expence spared to make the whole complete, with pictures, busts, statues, medals, and other curiosities worthy of being collected. It is thought that this building exceeds all in Europe for beauty and grandeur.
