The small church is close to the Porte de Saint Jean, next to the stairs to access the old city walls. Free entry during opening hours, stone interior with pebble floors.
Small church on the city wall near a city gate, which doesn't necessarily look like a church from the outside. But the door was open so we went in. Remains of frescoes can still be seen on the wall. Otherwise the church is almost empty.
Some people confuse this temple with another temple of St. John the Baptist, which is located at the exit from the St. John. This temple (XV century) is an inconspicuous building with a simple entrance. Inside, fragments of frescoes on the walls have been preserved. Entrance to the temple is free, but there are operating hours.
Small and simple church. Without furnishings. Free admission.
