Chiesa di SS Giovanni e Paolo

While there’s little of interest at this much-tweaked 4th-century church, the Roman houses that lie beneath it are fascinating. According to tradition, the apostles John and Paul lived in the Case Romane (06 704 54 544; www.caseromane.it; adult/12-18yr & over 65yr/under 12yr €6/4/free; 10am-1pm & 3-6pm Thu-Mon) before they were beheaded by Constantine’s anti-Christian successor, Julian. There’s no direct evidence for this, although research has revealed that the houses were used for Christian worship. There are more than 20 rooms, many of them richly decorated. Entry is to the side of the church on Clivo di Scauro. Guided tours are available in English on request.
