Opposite the Church of St. Paul the Apostle, there is a small building, which today houses the Ecclesiastical Museum.

This building is an excellent experiment in seismic architecture by Professor Per. Paraskevopoulos, who rebuilt it almost single-handedly, applying the technique of combining reinforced concrete and special cement board construction.

The important exhibits of the Ecclesiastical Museum have recently been transferred to a specially designed area of the Krokideion Hall, located in the building complex of the Episcopate of the Holy Metropolis of Corinth.
