The Museum of Badalona, founded in 1955, is one of the most fascinating cultural institutions in Catalonia, as it allows visitors to take a true journey back in time to the Roman era. Its greatest treasure lies underground, where the museum protects and exhibits the impressive archaeological remains of the ancient Roman city of Baetulo, founded in the 1st century BC. In this vast underground space of almost 3,400 square meters, perfectly adapted for museum display, one can stroll through the original streets, discover the remains of the baths, admire exceptional mosaics, and observe the ancient shops and sewers. In addition to this exceptional enclosed site, the main building houses permanent exhibitions with highly valuable pieces, such as the famous "Venus of Badalona," and is responsible for preserving and disseminating the rich historical heritage of the city, making it an essential reference for lovers of archaeology and ancient history.
