Fuentidueña de Tajo Castle is a large, irregular building standing on a hill which dominates the Town and the Tagus River. It is believed to have been built during the 12th century and has been extended and rebuilt later on in the 14th century. It is related to the Kings, Alfonso VI and Alfonso VIII.
It still has a wall and part of the cylindrical towers on the sides. The two sections composing it are separated by an interior moat. It is still possible to see the Homage Tower opposite the Town.This castle was the Headquarters of the Kingdom in the time of Da Urraca, wife of Alfonso I the Warrior; legend has it that at night she used to walk through the hidden corridors to visit the Moors.
The provincial Governor, Pedro Manrique, was imprisoned in this Castle by order of Juan II. Álvaro de Luna, Marquis of Villena, was also made prisoner for his discrepancies with the Order of Santiago; he later became the proprietor of the Castle.
The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
