A stairway through the green door on your left leads to the bare Coenaculum, identified by most as the site of the Last Supper. One of the reasons for its no-frills appearance is that Britain, in an effort to avoid sectarian disputes, passed a law during the Mandate forbidding any changes, including decorations, to be made in the church. During the 15th century, the building was used as a mosque and the mihrab is still visible in the southern wall. Beware the little old lady warning you about Armageddon. (Open daily 8:30am-4pm.) Below the Coenaculum is the beit midrash (study room) of the Diaspora Yeshiva, where many American students learn Torah. Every Saturday night between September and May, visitors are welcome to come sway to live Hasidic rock music. (8:30pm; tel. 71 68 41.)

To enter David’s Tomb, go out the green door and turn left. Above the blue velvet-draped tomb in the small cave, the silver crowns, not always displayed, represent the number of years since Israel gained independence. Archeologists refute the authenticity of the site because Mt. Zion was never encompassed by David’s walls, and it is written that kings and only kings were buried within the city. (Tomb open daily 8am-5pm. Free.)
