3. The Remains of the Roman Forum, commenced by Constantine II., embedded in the walls of an hotel in the Place du Forum.
THE GREEK THEATRE AT ARLES.
The two pillars formed part of the proscenium, and in the Middle Ages were used as a gibbet.
4. The Roman Tower of La Trouille (near the Musée Réattu—a small picture-gallery) is all that remains of the magnificent palace built by the Emperor Constantine between 306 and 330 A.D.
5. The Archæological Museum in the Church of St. Anne contains a magnificent Roman collection, including carved sarcophagi, altars, statues, and inscriptions.
6. The Cathedral of St. Trophime is opposite the museum. The Romanesque façade, dating from 1221, is a beautiful piece of architecture, enriched with statues and a bold arch supported by columns. The cloisters are intensely interesting, having been built in different periods—north and east sides Romanesque of the twelfth and thirteenth centuries, west about 1380, and south about 1505.
7. The Avenue des Alyscamps is the Roman cemetery of the city, just without the ramparts, put up during the reign of the Emperor Constantine. On either side of the avenue there are altogether 153 stone sarcophagi, the 33 large ones having retained their lids. The Alyscamps, when consecrated as a Christian burial-place, became so famous that bodies were brought great distances in order that they might enjoy the privileges supposed to be the lot of those who were buried there.
8. Church of St. Antoine, an interesting Gothic building.
