Calalzo is an ancient hamlet, as proved by the 2500 years old archaeological finds of Lagole. Around 500 B.C. here rose a temple, and its bronze statues and inscriptions are now kept in the Museum of Pieve di Cadore. Around the end of the 19th century the first modern eyewear factory was founded, by the Molinà stream. This factory was the forerunner of today's eyewear industry, that changed Calalzo in one of the most important industrial and commercial centers of the northern Belluno province thanks to the quality if its eyewear, known all over the world.
