The Basilica of Santo Stefano (known locally as the Sette Chiese, or Seven Churches), set on the large, triangular Piazza di Santo Stefano, is among Bologna’s top attractions, and a highlight of any city walking, bike, or Segway tour. Visitors enter the 11th-century Chiesa del Crocifisso, where the remains of Bologna’s patron saint, St. Petronius, lay until it was moved to the Basilica di San Petronio in 2000. The route then passes through a maze of pretty courtyards to the Chiesa del Santo Sepolcro, the Chiesa della Trinitá, and the Chiesa Santi Vitale e Agricola, Bologna’s oldest church, which was constructed with fragments of pilfered Roman flooring and masonry. The complex also houses a museum with a collection of religious paintings, sculptures, and other artifacts. In addition to the Basilica of Santo Stefano, guided tours of Bologna generally include other famous landmarks, including Piazza Maggiore and the Basilica of San Petronio, the Two Towers, and the Church of San Domenico.
