Stop by Catalan Ethnographical Museum and gain an insight into past civilizations. Who knows, you may uncover some unusual traditions and beliefs you never even knew existed.
This exhibition of human history in Sants-Montjuïc is well-liked by travelers, so leave a spot for it on your to-do list. Don't think that's all there is to do here, though. There are many more spots ready for you to appreciate after Ethnological Museum of Barcelona. Sagrada Familia, La Rambla, and Plaça de Catalunya are not far away.
