Torre Bellesguard, also known as Casa Figueras, is Antoni Gaudí's hilltop house in Barcelona, where royal history, a castle-like silhouette, and a calmer mood make the visit feel very different from his busier city icons.
Book an entry ticket first, because it lets you choose between the flexible audio-guided visit and the fixed guided tour, and prebooking makes this short daily opening window much easier to use.
