San Felices de los Gallegos Castle has an historical purpose as the frontier stronghold between Portugal and Castile. The enclosure with medieval origins is protected by the castle and the walls which were built in successive periods. The wall, built of stone blocks with adjoining square towers, dates from the 13th century and encircles a spacious bailey. The keep dates from the 15th century, and a third fortified enclosure with bastioned walls dates from the 17th century.
Inside the walls, it is worth noting the parish church (12th-13th centuries) in the transitional Romanesque style (façade and belltower) modified in the Gothic-Renaissance period (16th century), with three naves and a main chapel.Highlights of its civil architecture are buildings such as the Town Hall (16th century) and the Alhóndiga, the former hospitals of Rocamador and La Misericordia, and various noble mansions with their carved coats of arms (16th to 18th centuries), such as the houses known as Los Mayorazgos, El Corregidor and Los señores de Ron.
References: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.
