Barcelona's famous architectural son, Antonio Gaudi, left his mark on the city nowhere more prominently than in the gardens of the Parc Guell. The park, sited on Camel Hill offering splendid views of the city, was originally planned to be a garden city suburb, but only two houses were completed before it was turned into a public recreational park. The gardens are festooned with examples of his work, including flights of stairs, columns and a plaza decorated with mosaics. The pink fairytale house standing at the entrance to the park was once home to Gaudi and his niece, but is now a museum containing some Gaudi-designed furniture, décor, drawings and portraits of the architect.
