1. City Overview, September 2011. Situated on the northern coast of Crete, Rethymno is home to forty thousand people and is the island’s third largest city. In truth though this is a city in name only, comprised as it is of leafy, peaceful streets, a still, picture-perfect harbour and languid, slow-moving locals. With a reputation as one of the best-preserved mediaeval cities in Greece, embark on a self-guided walking tour and you’ll be treated to some stunning Venetian architecture, a number of Turkish mosques and a couple of Catholic churches.
