In the centre of the town lies the main square Piazza Sant’ Oronzo, which marks the end of the Via Appia - the Roman road to Southern Italy. Near a tall 17th century column topped by a statue of the city’s patron saint is the Palazzo del Sedile, a loggia built in 1592. Adjoining the loggia is the doorway of the little church of San Marco, founded in 1543 and once used by the small Venetian community in Lecce. On the south side of the square are the excavated remains of a Roman amphitheatre which dates from the second century. It was buried under Piazza Sant’ Oronzo and only discovered in 1929 and has since been partially excavated. More of its remains are still buried under adjacent buildings. The seating tiers and part of the floor have been excavated as the photographs show and today are used for concerts and performances, it has been estimated that the whole amphitheatre would have held about 25,000 spectators.
