The external facade and the column on the left
The facade and the column outside the monument
The entrance façade is surmounted by a small bell gable dominated by a bell dated 1682 and called, as in the oration dedicated to San Michele reported in bas-relief around it, "Miracle Bell". The bell tower previously stood in the rear part of the structure, later when the above facade was built it was moved to the front.
To the left of the small entrance facade is a fluted column surmounted by a metal cross. Its construction, which in an unlikely way, is attributed to the will of Gregory the Great's parents by the hand of General Tulliano XI, leader of Sipontine weapons (end of the 6th century), the date of construction is not really known.
