Santa Maria degli Angeli e dei Martiri
The porticos around the piazza, built in 1887–98 by Gaetano Koch, were in memory of the ancient buildings on the same sites, while the basilica of Santa Maria degli Angeli e dei Martiri on the piazza is based on a wing of the baths (with its architect Michelangelo, using the tepidarium as one of the wings of its spacious Greek cross plan).
