This hill overlooking the south side of the port is popularly said to have been named Mont Juif for the Jewish cemetery once on its slopes, though a 3rd-century Roman document referring to the construction of a road between Mons Taber (around the cathedral) and Mons Jovis (Mount of Jove) suggests that in fact the name derives from the Roman deity Jove, or Jupiter. Compared to the human warmth, hustle, and bustle of Barcelona, Montjuïc may feel remote, but its museums are all undoubtedly among Barcelona's must-see sights.
