Charterhouse of Monegros Monument · Lanaja, Los Monegros, Huesca The Charterhouse of Monegros, from the 17th century, was declared a Bien de Interés Cultural in 2001 (Spain's highest level of heritage protection) and is one of the three charterhouses of Aragon, with murals by Manuel Bayeu. The Carthusians of Saint Bruno settled at the site as early as 1507, giving rise to the Charterhouse of the Virgin of the Fountains, in the municipality of Lanaja. Following the Mendizábal disentailment in the 19th century, the property passed into the hands of the House of Bastaras, its current owners, who registered it in the neighbouring municipality of Sariñena in order to benefit from lower taxation.
