OTE Telecommunications Museum preserves and exhibits important collections, closely connected with the history of Greek telecommunications and thus OTE, as well as the history of Greece and the evolution of its society.
The Society of Studies of the Lavrion Region founded the Mineralogical Museum of Lavrion, with the aim of highlighting one of the most important aspects of the region's natural wealth. The Museum is dedicated to the memory of A. Kordellas (1836-1909), the major contributor to the revival of modern-day Lavrion. The Lavrion area is one of the most favoured sites in the world from the point of view of its variety of minerals, and samples of its minerals are displayed in the greatest Natural History Museums.
