• Star-pricked dome over the main hall, where small holes scatter daylight across the ceiling like a night sky
• Mosaic chimney roof kids can walk among, each cone clad in colored broken tile
• Basement horse stables with mushroom-shaped brick columns, reached by a spiral carriage ramp

An early Antoni Gaudí mansion, built 1886 to 1888 for the Güell family. The tour runs from a brick-columned basement stable, where carriage horses were kept, up to a central hall topped by a dome pierced with small holes that let light fall like stars. The flat roof is set with cone chimneys covered in broken-tile mosaic.
