This small museum has an excellent collection of artefacts tracing the prehistory of the island of Thera. They are well-organized, with labels in English. The stars among the exhibits are the wall paintings from the excavations at Akrotiri and a small, but very beautiful golden ibex, but the whole museum is quite fascinating. The museum is surprisingly uncrowded even in the high tourist season so you can really enjoy the exhibits! If you visit the ruins at Akrotiri, adding a visit to the museum is an absolute must. Seeing both will give you a much better picture of the Minoan settlement on the island.
