What is it? You can take the lift or stroll through the modern Parque de la Ereta to reach this mighty cliff-top castle. Built over a ninth-century Arabic fortress, the current construction dates to the eighteenth century and is home to the city’s history museum.
Why go? The views from up here are truly extraordinary, and all the more worth it if you’ve opted for the sweaty climb uphill rather than the lift. You can march across parade grounds, soak up the views, and stop for a well-deserved cold drink at the café.
