Among the public buildings still recognizable are a theatre capable of accommodating 6000 spectators, a naumachia (circus for naval combats) and several temples, of which the largest was probably the grandest structure in the city, possessing a portico of Corinthian pillars 38 ft.
In 2 B.C. Augustus, at the dedication of the temple of Mars Ultor, exhibited a naumachia between Athenians and Persians, in a basin probably in the horti Caesaris, where subsequently Titus gave a representation of a sea-fight between Corinth and Corcyra.
There are also remains of a much smaller theatre (the so-called Odeum), and some large cisterns; a large bath or tank which was apparently open, known as the Naumachia, measures 4262 ft.
