Ialysos, is a town and a former municipality on the island of Rhodes, in the Dodecanese, Greece. Since the 2011 local government reform it is part of the municipality Rhodes, of which it is a municipal unit. It is the second-largest town on the island of Rhodes. It has a population of approximately 12,000, and is located eight kilometres west of the town of Rhodes, the island's capital, on the island's northwestern coast. The town is situated near the site of the ancient Doric polis of Ialysos, homeland of the famous ancient boxer Diagoras of Rhodes. The municipal unit consists of the town Trianta/Ialysos and the surrounding areas. While official sources use Trianta as a name for the town, and Ialysos for the whole municipal unit, unofficial usage tend to favour Ialysos to describe both the modern town and the municipal unit. Until the mid-1980s Trianta/Ialysos was a village with a population of around 2500 people, but during the following years population grew to an official 10,107 at the 2001 census, as it to an increasing degree became a suburban district to the town of Rhodes. Ialysos has in addition become a tourist destination, with several hotels and resorts located on the coast, especially in the new settlement of Ixia, situated between the towns of Ialysos and Rhodes. Being on the usually windward north-western coast of the island, it is also a noted location for wind-surfing. The municipal unit has a land area of 16.700 km², the smallest of any on Rhodes.
