A window onto the recent past of Crete opens up for the visitor at the Folklore Museum of Aghios Nikolaos. Established in 1985 by the Cultural Association of Eastern Crete, it is housed on the ground floor of the Port Authority building, one of the oldest buildings in town, which is located by the lake. There are many displays of traditional Cretan handcrafts, unique to the region such as textiles, woven goods and embroidery of intricate detail and imaginative designs.
A model of a traditional Cretan house, equipped with household goods and cooking implements has also been set up here. Books, manuscripts, old photographs, paintings, weapons, coins, multi-coloured woven rugs and examples of traditional Cretan costumes complete the collection. These items have been donated to the Folklore Museum in recognition of the valuable role it plays in the preservation and display of the rich traditional heritage of everyday life in Crete.
A preservable neo-classical building of end of 19th century - at this period, residence of tradesmen of “comestible” plant products of Mirabelo - entertains Museum “[IRIS]” with selectively plants well-known for the wealth and the variety of Cretan flora.
