This fairy-tale castle upriver from Abrantes stands atop a cone-shape hill, commanding superb views of the Tagus River. It was built in the last years of the 12th century by the Knights Hospitaller under the command of King Sancho I. In 1194, this region was threatened by the Moorish forces who controlled the lands south of the river. The expected attack never took place, leaving the present structure little changed from its original design, as one of the country's most complete examples of medieval military architecture. The walls of the keep, which stands in the center of the courtyard, are some 12 feet thick, and on the ground floor is a great cistern of unknown depth. According to local lore, an orange dropped into the well will later appear bobbing down the river. The castle is reached by car in 30 minutes via the N244–3 through pine-covered hills to Chão de Codes, then the N244 south toward Gavião. There are four trains a day to Belver from Abrantes (a 25-minute ride).
