Also referred to as “The Celio,” Caelian Hill is the southern-most of the great seven hills of Rome. This hill features two high pointsLarger Caelian (Caelian Major) and Smaller Caelian (Caelian Minor)and is divided into two main sections by the Via Claudia: the lower eastern slopes and the west. Caelian Hill boasts several interesting and famous structures. In the east, three churches stand out prominently: San Clemente, S.S. Quattro Coronati, and Santo Stephanus Rotondo, all of which are surrounded by a sea of restaurants, bars, and local shops that offer comfort and a nice slice of Roman culture and cuisine. The narrow roads of this locale lead northwardly straight into the heart of San Giovanni in Laterno, the Cathedral of the Bishop of Rome.
Farther west lays the great Temple of Emeror Claudius, surrounded by spacious temple courts. The famous colosseum sits at the foot of the hill where it can be viewed from many locations. Most impressive, however, is the massive aqueduct, which traverses the hill and carries fresh water into the heart of Rome. Tourism into the hill is allowed via walking or bus. The nearest metro stations, Circo Massimo and Colosseo, provide bus trips. Buse 81 is the most convenient, but the Trans Number 3 stops at the lower slopes. Independent treks on foot can bring enough adventure to last for days.
