Tresana, a village perched above the valley of the Osca stream—a tributary of the Magra River—is home to an imposing castle that dominates the landscape. In 1164, the Malaspina family received permission from Emperor Frederick Barbarossa to build a turris sana ("solid tower"), from which the name Tresana is derived.
This ancient castle served as a defensive stronghold, controlling the route that connected the Magra Valley to the Ligurian hinterland. In addition to the castle, Tresana also boasts the historic Church of San Giorgio, which has stood since 1470. Featuring Baroque architecture of rare beauty, the church enriches the cultural and historical heritage of this charming Lunigiana village.
