House of Harmony Monument · l'Hospitalet de Llobregat, Barcelonès, Barcelona La Harmonia is a Renaissance manor house in l'Hospitalet de Llobregat, declared a cultural asset of national interest. It was built in 1595, possibly on the site of the Torre Blanca estate, mentioned since the 11th century, next to which a small hospital arose at the end of the 12th century that gave rise to the population centre later known as l'Hospitalet. It is a large manor house with a quadrangular floor plan and a four-sided roof, three hierarchically arranged storeys on the façade, a voussoir-arched round portal and a circular turret that gives it the air of a fortified house. Its current name comes from a society that occupied the building between 1866 and the 1930s; today it is the headquarters of the Ateneu de Cultura Popular.
