San Cesareo in Palatio

San Cesareo in Palatio is a church building in Rome featuring a single nave with a wooden coffered ceiling decorated in blue and gold. The space contains artistic elements spanning multiple periods, from medieval mosaics to painted wall surfaces.

The church originated in the 8th century, built atop Roman bath ruins that contain a 3rd-century Neptune mosaic underground. Medieval mosaics later placed here came from a significant basilica elsewhere in the city.

The church blends different artistic periods within its space, from medieval mosaics to early 17th-century frescoes by notable painters. Visitors can observe how these traditions coexist in a single, modest interior.

The site sits near Porta San Sebastiano and welcomes visitors interested in exploring its layered history. It helps to spend time looking closely at the artistic details, since the interior is compact and filled with work from different hands.

Beneath the church lie Roman luxury baths with a well-preserved mosaic showing diving and fishing scenes, rarely visible to visitors. These underground spaces offer an uncommon look at classical Roman life before the church was erected above.
