Puig i Cadafalch’s Casa Terrades, completed in 1905, is better known as the Casa de les Punxes (House of Spikes) because of its pointed turrets. Resembling a medieval castle, the former apartment block is the only fully detached building in L’Eixample, and was declared a national monument in 1976. Since 2017 it has been open to the public. Visits take in its stained-glass bay windows, handsome iron staircase, and rooftop. Guided tours in English lasting one hour depart at 4pm.
Various other tour options include a night-time tour with a glass of cava (€23).
