Casa dos Bicos is one of Lisbon's most striking historical landmarks, instantly recognisable for its unusual façade covered in diamond-shaped stone "spikes" that give the building its name. Built in the early 16th century, it reflects a blend of Italian Renaissance influence and Portuguese Manueline style, and it has remarkably survived the 1755 earthquake that reshaped much of the city. Today, it is carefully restored and serves as a cultural space and the home of the José Saramago Foundation, often hosting exhibitions and events that connect Lisbon's layered history with contemporary Portuguese literature and culture.
