Porte de Boisville Its ogival portal opens into a thick quadrangular massif where there was a room for operating the portcullis. We can still see the groove in the thickness of the walls. On the left and right two small funnel-shaped spaces allowed the defenders to observe and repel the enemies who appeared on the bridge. The gate was topped by a building serving as a guardhouse which was demolished in 1761. The guarding of these doors and their keys was in the troubled times of the Hundred Years' War the subject of concern for the inhabitants and also a source of quarrels and trials between the city and the abbey. This gate is preceded by a bridge of 5 stone arches, the one adjoining the gate was built in 1774 and replaced a drawbridge which defended the entrance.

This church in Romilly-sur-Aigre was dedicated to Saint Peter (Saint Pierre). Simon, nicknamed Peter (Rock), was a fisherman on the Sea of Galilee when he - together with his brother Andrew - was called by Jesus Christ to be "fishers of men". According to Catholic understanding, he is the supreme apostle, and the two millennia-long line of popes - currently Francis - are his successor. On statues and paintings, Peter is almost always depicted with two keys in his hand; this attribute refers to the biblical saying in Matthew: “I will give you the keys of the kingdom of heaven; Whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven” (Chapter 16, verse 19). Peter and Paul are also known as the “Princes of the Apostles”; their common feast day in the saints' calendar is June 29th.
