This polygonal silo, designed by an unknown architect, is an imposing presence in Huerta de Salud Park, a former recreational site first owned by the Duke and Duchess of Frías that was turned into an agricultural-industrial complex in the late 19th century by lawyer Pedro Tobar. The silo has been repurposed as a space for exhibitions and cultural events. It has a reading room and a viewpoint on the top floor that can hold one hundred people and offers views of Cuatro Torres Business Area, Barajas and Madrid’s mountains.
