Located at the top of Alzuza, a small village located 8 kilometres east of Pamplona, the Oteiza Museum is home to the personal collection of Jorge Oteiza, one of the greatest sculptors of the 20th century.  The Museum contains a representative selection of his work consisting of 1,650 sculptures, 2,000 pieces from this experimental laboratory, and numerous sketches and collages.  The building, a large cube of reddish-coloured concrete, is the work of one of Oteiza’s closest friends and collaborators, the Navarrese architect Francisco Javier Sáenz de Oiza. It includes the house occupied by Jorge Oteiza for two decades, enabling visitors to get to know the peculiar way and the intimate atmosphere in which he worked.
