If you're eager to add some extra culture to your getaway, put Martorell Museum on your itinerary. Check if guided tours are available or just wander around at your own pace.
This museum is on the to-do lists of many travelers to Ciutat Vella. But Martorell Museum isn't the area's only highlight. Sagrada Familia, La Rambla, and Plaça de Catalunya are some other interesting attractions close by.
