This is the famous Gaudi park located just outside of Barcelona. It takes about an hour to get there, but there is a bus that runs there. The park was orginally built as a housing settlement of sorts for the elite, but actually failed in this endeavor. The buildings there are famous for the Gaudi architecture. Most of the Gaudi images seen on postcards are from this park. The benches are especially interesting with the mosaic-style backs. These days, it is not especiallly safe so it is best visited during the day. The trek out there is worth it though, especially if you want to see what Gaudi architecture really is.
