Saints Sergius and Bacchus Church, also known as the Abu Serga Church as well as the Cavern Church, is an important historical and religious landmark in Cairo, Egypt. The church is supposed to be built on the spot where Joseph, Mary and baby Jesus rested at the end of their journey into Egypt. The church is dedicated to Sergius and Bacchus who were soldiers in the 4th century that were killed by the Roman Emperor Maximian and achieved martyrdom and sainthood.

The church is one of the oldest in Egypt and dates back to sometime in the 4th or 5th century. It is located near the Babylon Fortress in Cairo and it was believed that Joseph may have been one of the people to work on the construction of the fortress. We visited the Abu Serga Church as part of a tour of the section of Cairo  known as Coptic Cairo where there are a variety of historical sites.

The interior of the church is quite fascinating and contains a variety of ancient relics. It is a popular location for tourists to visit and you will find yourself in a line of people as you make your way through the actual cavern inside of the church. There is also a well within the church that is believed that the Holy Family drank from. With such historical, religious, and cultural significance, visiting the Saints Sergius and Bacchus Church is definitely worth doing while you are in Cairo.
