This was the first centrally planned templelike church of the High Renaissance (1485-1506), a not entirely successful exercise in Brunelleschian theoretical architecture by Giuliano da Sangallo. The light plaster walls with pietra serena accents and Andrea della Robbia friezes and tondi are pleasantly evocative, but the monumental space can leave you a little cold. The interior contains a St. John the Baptist statue over the font by the architect's son Francesco and the miraculous 14th-century fresco of the Madonna with Child and Two Saints that the church was built to house. The stained glass was designed by Domenico Ghirlandaio.
