Several Modernistas had a hand in this imposing neo-Gothic former seminary, looming over the west end of town. Domènech i Montaner contributed its medieval flavour. It’s now an international Spanish language and culture study centre, the Centro Universitario CIESE-Comillas. Thirty-minute visits to the elaborate interiors and patios are guided in Spanish (with leaflets in English available). Access to the grounds on foot is free.
