Camp Nou is the home stadium of FC Barcelona. It was built in the 1950s to replace their old stadium, as the club's popularity grew and they won two league titles. The first steps towards building a new stadium were taken in 1950, when the club president signed an option to purchase land for the stadium. The FC Barcelona museum was first proposed in the 1920s but was not opened until 1984. It has since been expanded three times and now covers 3,500 square meters. It receives over 1.2 million visitors per year, making it the most visited museum in Catalonia. The museum helps explain the social and cultural impact of the club and is considered one of the best football museums in the world.
