The sepulchre of the monks
The remainders as well as the heap of stones of the ploughed up part suggest a building of octagonal form, formed of 4 rectangular vaults grafted at the ends of a Greek cross, connected between them by four circular niches. We can reconnize the “baptistry” type .
It is called around sepulchre bus extended the cemetery from the monks. The church was used as funeral vault. However, it is as possible as this octagonal form is inspired by the Holy Sepulchre of Jerusalem.
