The half bay before the sanctuary has a doorway on each side. Above these are a pair of statues in round-headed niches by Juan Adán. They seem to be his only work in Rome, and presumably were installed in the 19th century restoration.

The presbytery has a large arch on each side, echoing those of the side chapels, and into each is inserted a cantiora or raised balcony for singers and musicians. They are supported on marble columns, and were installed in 1829. The church's organ was installed here, in two sections, in 1929.
