Rethymno (Greek: Ρέθυμνο, [ˈreθimno], also Rethimno, Rethymnon, Réthymnon, and Rhíthymnos) is a city of approximately 40,000 people in Greece, the capital of Rethymno regional unit on the island of Crete. It was built in antiquity (ancient Rhithymna and Arsinoe), but was never a competitive Minoan centre. It was, however, strong enough to mint its own coins and maintain urban growth. One of these coins is today depicted as the crest of the town with two dolphins in a circle.
This region as a whole is rich with ancient history, most notably through the Minoan civilisation centred at Kydonia east of Rethymno. Rethymno itself began a period of growth when the Venetian conquerors of the island decided to put an intermediate commercial station between Heraklion and Chania, acquiring its own bishop and nobility in the process. Today's old town (palia poli) is almost entirely built by the Venetians. It is one of the best preserved old towns in Crete.
The town still maintains its old aristocratic appearance, with its buildings dating from the 16th century, arched doorways, stone staircases, Byzantine and Hellenic-Roman remains, the small Venetian harbour and narrow streets. The Venetian Loggia houses the information office of the Ministry of Culture. A Wine Festival is held there annually at the beginning of July. Another festival, in memory of the destruction of the Arkadi Monastery, is held on 7–8 November.
Rethymno (Greek: Περιφερειακή ενότητα Ρεθύμνου) is one of the four regional units of Crete, Greece. Its capital is the city of Rethymno. Today its main income is tourism. The countryside is also based economically on agriculture and herding.
The regional unit Rethymno is subdivided into 5 municipalities. These are (number as in the map in the infobox):
The Rethymno prefecture (Greek: Νομός Ρεθύμνου or Ρεθύμνης) was created while Crete was still an autonomous state, and was preserved after the island joined Greece in 1913. As a part of the 2011 Kallikratis government reform, the Rethymno regional unit was created out of the former prefecture. The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.
