Viŀla Joana is a masia located in Vallvidrera in the middle of Collserola Natural Park. It is a two story building with a watchtower and lateral galleries. One of its most distinctive elements is the clock on the main façade.
Today, Viŀla Joana houses one of the branches of the Barcelona City History Museum (MUHBA). The museum deals with the history of the site, literature, and the Catalan poet Jacint Verdaguer, who died here in 1902.
