Like all Gaudí structures, Bellesguard is a mass of symbols and metaphors – evocations of King Martí and Catalan history in the bright, broken mosaic or trencadís benches, obscure references to nature. Religiosity and Gaudí could never be far apart: house and tower are 33 metres high, the reputed age of Christ at his death, and three balconies correspond to God the Father, Son and Holy Spirit. Other elements are stranger, such as the gorgeous eight-sided stained glass "Star of Venus" window, potentially a symbol of fertility, or even the Cathars, the medieval heretical sect that had been protected by the Catalan kings.
