The National Palace of Pena
The National Palace of Pena is the most famous castle in Portugal, due to its colorful appearance and its imposing location at the peak of the highest hill above the town of Sintra. It is a monument of national and international importance, and is recognized by UNESCO. The story of the Palace of Pena dates back to Middle Ages, when a chapel dedicated to the Lady of Pena was established. This eventually grew into a monastery and then a castle. The façade of the building is outstanding, and it borrows elaborate details from the Manueline and Moorish styles of architecture. The clever design of the palace ensured that it could be seen from anywhere in the surrounding gardens and forests.
