We’re standing at the intersection of the two oldest streets in the neighbourhood, Nena Casas and Alt Gironella. Before us stands a large Catalan Art Nouveau mansion, surrounded by a large garden. At the end of the 19th century, Tres Torres was farmland, scattered with woods and crossed by streams flowing down from the Collserola Mountains. This area was owned by Ramona Castellnou, better known as “la Nena Casas” (the ‘houses girl’), for the many houses and terrains she owned. The heart of her domain was here, where a farmhouse from the 17th century was transformed into the Catalan Art Nouveau tower that stands before us. It’s now owned by the Felipenses Congregation of nuns. This house, surrounded by beautiful gardens, combines silence, prayer, meditation and social activism. It also includes a series of multi-purpose spaces and housing for holding courses, concerts and conferences. The schedule of activities is available on the House’s website.
