The most interesting aspect of this museum is the building itself - a mosque with the only intact minaret in the Aegean Islands. The museum contains a clutter of Hellenistic statuary, Roman slabs and a collection of Turkish, Jewish and Armenian tombstones that hint at the island’s multi-ethnic past.

This museum benefits from a great location in a green environment on Saint Helen's Island. The Biosphere Museum is dedicated to preserving the environment and sustainability. Natural environments are recreated indoors. It is a great activity for families, and the sphere is very photogenic from the outside.

A former military cemetery from 1855 where you can see several graves from both the First and Second World Wars. From late February to the beginning of June, an impressive orchid garden blooms, adding beauty to this solemn place.

Further inland, in the southern part of the island, lie the so-called masticochoria (mastic villages). These well-preserved, fortified villages date from the 14th-16th centuries and were centres for the cultivation of mastic. Mastic is the sweet-tasting gum of the lentisk bush, which was exported all over the Mediterranean – and the area still produces around 300 tonnes of mastic every year. The most picturesque villages are Pyrgi, with its houses decorated in black and white geometric patterns called xysta Mesta, where towers and walls surround a baffling labyrinth of village streets as well as Olympoi and Vessa are all a worth a visit.
