The Roman Odeon of Kos is a well-preserved 2nd-century Roman theater built over the remains of an earlier public building. Originally serving as a venue for musical competitions and senate meetings, the structure features a semi-circular orchestra and a stage area. Nine rows of marble seats remain in the lower section, while the upper section, supported by vaulted galleries, was constructed with brick and stone. Excavations in 1929 by the Italian Archaeological School uncovered the site, revealing a foundation that rests on a base of local volcanic stone. The stage area contains a series of vaulted rooms that served as dressing areas for performers. Several original marble statues discovered here, including a statue of Hippocrates, were relocated to the Archaeological Museum of Kos. The site remains a primary example of Roman urban planning on the island.
