Torrelobatón Castle is one of the most important and best-preserved fortresses in Valladolid. In the historical epic film El Cid with Charlton Heston the castle played the role of Vivar, hometown of El Cid.
The castle was begun in 1406, when Don Alfonso Enríquez, 1st Admiral of Castile, obtained licence from John II to erect a fortress in Torrelobatón; the only fortification there was a modest stone enclosure surrounding the village. The castle was involved in the Revolt of the Comuneros against Charles I (Holy Roman Emperor Charles V).
It has a square ground-plan, with circular turrets at three of the corners and the keep set into the fourth, protecting the gate. The castle was surrounded by an enceinte, of which there are some remains, and a ditch, now mostly filled in. The entrance to the Torrelobaton Castle courtyard is through a gate with a round-headed arch protected by a portcullis. The keep is the most interesting feature of the fortress. Of considerable height, the upper part is protected by eight turrets supported on accordion brackets, one at each corner and one in the middle of each wall.

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.
