La Casa de les Punxes, or Terrades House, was designed by Puig i Cadafalch and built in 1905 at the request of the Terrades sisters who wanted to join up three properties they owned. The architect designed a medieval-style building resembling a castle. It features six towers, each crowned with a conical-shaped needle which give the building its popular name “The House of Needles”.
In 1975 it was declared a National Historic Landmark.
Being a privately-owned house, it is not possible to visit the interior.
