The Church of St Peter of Gallicantu, a Byzantine-style Catholic church located on Mount Zion, offers stunning views of the City of David and the village of Silwan, a Palestinian community. The current building, which has some interesting decorations such as stained glass windows, was completed in the 1930s on the site of earlier churches, including a Byzantine monastery. Inside, visitors can admire mosaics and remains from previous churches.
According to tradition, the church marks the spot where the Apostle Peter wept in regret after denying Jesus before his death. The Roman stairs next to the church are believed to have been used by Jesus on his way to Gethsemane.
