Castle of La Alameda, Medieval castle in Alameda de Osuna district, Madrid, Spain
The castle of La Alameda is a rectangular flint fortress with rounded corners in the Alameda de Osuna district of Madrid. It has two towers of different shapes, one square and one cylindrical, set at opposite ends of the structure.
The Mendoza family built the fortress in the mid-15th century as a fortified base in the region around Madrid. In the years after its construction, it served as a refuge for allies during power struggles in Castile.
The castle is part of Madrid's Museum of Origins network and hosts exhibitions on local history inside its rooms. Visitors can see the flint stone walls up close, which makes the building material itself a visible part of the experience.
The castle sits in the Alameda de Osuna neighborhood and is reachable by metro from central Madrid. It is worth checking opening days before going, as the interior rooms are only accessible when the museum is open.
Excavations beneath the castle uncovered traces of a settlement that existed around 2000 BCE, long before the medieval structure was built. This means the site was already a place of human activity for thousands of years before the Mendoza family chose it.
