Question

Christians adapted the Roman basilica and used it for public worship. Where in their churches did they place the altar?

Answer 1

The correct answer is - At the Apse.

The apse is a recess which is sometimes rectangular but usually semicircular, in the wall at the end of a Roman basilica or Christian church.

The apse in the Roman basilica frequently contained an image of the Emperor and was where the magistrate dispensed laws. In the Early Christian basilica, the apses contained the "cathedra" or throne of the bishop and the altar.
