The Castle of the Moors is a hilltop medieval castle built by the Moors in the 8th and 9th centuries. It was an important strategic point during the Reconquista, and was taken by Christian forces after the fall of Lisbon in 1147. It is classified as a National Monument, part of the Sintra Cultural Landscape, a UNESCO World Heritage Site.
During the second half of the 12th century, the chapel constructed within the walls of the castle became the parish seat. This was followed by the remodelling and construction under the initiative of King Sancho I of Portugal. In 1375 King Ferdinand I of Portugal, under the counsel of João Annes de Almada, ordered the rebuilding of the castle. While the structure was well fortified by 1383, its military importance was progressively diminishing as, more and more, the inhabitants were abandoning the castle for the old village of Sintra.
By 1493 this chapel was abandoned and later only used by the small Jewish community of the parish. The Jews occupying and using the structures in the castle were expelled by Manuel I of Portugal, and the castle was completely abandoned.
The 1755 Lisbon earthquake caused considerable damage to the chapel and affected the stability of the castle. By 1838 the towers were already in ruins, when in 1840 Ferdinand II of Portugal took up the task of conserving and improving the condition of the castle.References:
Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
