Built in the 3rd century AD, it remained the main access to the town until the 1930s, when it became too low on the water level and had to be demolished. The old bridge was laid out on the riverbed, but can still be seen emerging from the water, while a modern bridge replaced it. The nearby area is a very good spot to enjoy Rieti's natural beauties: Velino's water is clear, the riverside is covered by a nice lawn, and ducks use the old bridge as a nest. There are nice cafes and pubs facing the river.
It maintains the original 16th-century wooden doors.
17th-century fountain at the centre of the square.
It consists in a display of sculptures, coins, goldsmithery and objects from the prehistoric, Etruscan, Hellenistic and Roman periods, including an iron age urn found near Rieti.
St. Dominic church has an architecturally significant convent, well worth a visit. It develops around the Blessed Colomba cloister, with a beautiful Italian-style garden and a portico decorated by frescoed lunettes illustrating the life of the blessed Colomba. At one side of the cloister, there is the St. Peter the Martyr Oratory, a small chapel that houses an astonishing fresco of the Last Judgment, painted by brothers Lorenzo and Bartolomeo Torresani between 1552 and 1554. Sadly, it is almost impossible to visit the oratory and the cloister, since it's part of the military area of an Italian Army barracks (caserma Verdirosi), and the military allows touristic visits only on special occasions (e.g. "giornate FAI"). This is a real shame, since it is arguably the most important fresco in the whole city!
The so-called geographical centre of Italy might seem like a gimmick to attract tourists, but Rieti was nicknamed "Umbilicus Italiae" ("navel of Italy") even in Roman times. The exact point is at St. Rufus square, recorded by a multilingual plaque and a monument which locals call "caciotta", as it resembles a round cheese.
It's a small alley that perfectly represents the typical features of mediaeval cities, with arches, ladders and narrow passages. It's not the cleanest spot in town, although it has been repaved.
