San Lorenzo in Lucina has been standing since the fourth century, and it is believed to have been built on an ancient temple dedicated to the Roman goddess Juno. Today, the church is a minor basilica dedicated to Saint Lawrence, a Roman martyr, and little of its original architecture remains. Instead, the building mixes everything from repurposed Roman columns and a 12th-century portico and bell tower to an ornate 17th-century baroque interior with a few 19th-century frescoes interspersed.
See the basilica on walking or Segway tour of early Christian churches and sites, including San Clemente and the Basilica of St. Paul Outside the Walls. As San Lorenzo in Lucina is in Rome’s historic center, pair a visit of the church with a tour of nearby highlights, including Piazza di Spagna and the Trevi Fountain.
