Although we had only planned an hour, we ended up spending the entire afternoon wandering around this charming open-air museum with facades and some interiors constructed to illustrate many different kinds of Spanish architecture from all ages and all types. Originally built for an international exhibition at the end of the 1920s, the "village" was not torn down as planned due to its unexpected popularity. Definitely choose the audio guide - I'm sure I wouldn't have learned as much without all the interesting information and anecdotes I could hear as we walked around. We were there in mid-February so not all the shops and cafes were open yet, but we were able to see glassblowers at work, and really enjoyed the combination of architecture, the modern paintings and sculptures at the Fundació Fran Daurel for example, the beautiful vistas of Barcelona you can get along the way, and the overall friendliness of the visitors and staff.
We would definitely go back and spend then a full day wandering around and learning more about all kinds of Spanish architecture and history at one place and experiencing more of the arts and crafts displayed. We two adults found more than enough to keep us occupied and fascinated, but there are also some wonderfully sounding activities for children too.
