Solovki (or the Solovetsky Islands or the Solovetsky Archipelago) are a group of islands in the White Sea. They are well known for primal labyrinths, sacred sites and burial mounds, as well as grand history of the St Transfiguration Monastery and dark page of GULAG. At present there is a large federal museum-nature reserve and the Solovetsky Monastery. The settlement on the island has 800 residents. Different tours and excursions are available on the islands.
