When the temple was turned into a church the entrance was moved to the rear, and the rear wall of the cella had to be destroyed. The spaces between the columns were closed, while 12 arched openings were created in the cella, in order to obtain a structure with one nave and two aisles. The pagan altar was destroyed and sacristies were carved out in the eastern corners. The sepultures visible inside and outside the temple date to the High Middle Age.
