Immerse yourself in the atmosphere of the past at one of the most unusual locations Greece has to offer. The Leros War Museum, also known as the "Tunnel Museum," is a unique historical site located in the Merikia area on the island of Leros. It is housed in an authentic Italian artillery bunker carved into the rock in the first half of the 20th century.

Opened in 2005, the museum is considered one of a kind due to its underground location. Inside the winding tunnel passages, an impressive collection of World War II artifacts is displayed: from weapons and uniforms to personal letters and photographs of soldiers from various armies—Germany, Italy, Great Britain, and the USA. The unique acoustics and the cool air of the stone walls create an unmistakable feeling of being at the heart of historical events.
The exhibition covers not only military technology but also the daily life of that era. Visitors can see a restored medical block with authentic surgical instruments and an operating table, as well as rare exhibits related to the local resistance. This site is rightfully considered one of the island's main attractions, blending the memory of heroism with the technical power of the past.
