Kourion is an ancient Greek city located in the Limassol District of Cyprus. It was inhabited from the Neolithic period until the Byzantine era and was one of the most important city-kingdoms on the island during the Hellenistic and Roman periods.

The city's acropolis is situated on a hill overlooking the Mediterranean Sea and was first fortified in the 13th century BC. The ancient city's most notable feature is the Greco-Roman theatre, which dates back to the 2nd century BC and is still used for cultural events today. The theatre, which could seat up to 3,500 people, was excavated and reconstructed in the 1960s.

Other notable features of the ancient city include the public baths, the House of the Gladiators, and the House of Achilles. The public baths were built in the 2nd century AD and consisted of a series of hot and cold rooms, a frigidarium, tepidarium, and caldarium. The House of the Gladiators was a large villa complex that contained several courtyards, private baths, and a mosaic depicting a gladiatorial contest. The House of Achilles contained several rooms, frescoes, and mosaics that depict the life of Achilles.

Kourion was largely destroyed by an earthquake in the 4th century AD, but was later rebuilt and inhabited until the 7th century AD. Today, the site is a popular tourist destination and has been designated a UNESCO World Heritage site. Visitors can explore the various ruins and exhibits in the archaeological park, which also includes a museum and a visitor's center.
