Fodor's Expert Review Castelo de Montemor-o-Novo
One of the most beautiful in the region, this huge castle towers over the city. It includes an ancient porta da vila (city gate) that could be closed during attacks, a casa da guarda (guard station), and a dramatic torre do relogio (clock tower). You can climb onto the outer fortifications and walk around the complex for a 360-degree view of the town and the sweeping plains beyond. It's also a pleasant walk up to the castle through the winding, steep side streets lined with 17th-century manor houses and ornate doorways.
