The University of Salamanca was founded in 1134 and given the Royal charter of foundation by King Alfonso IX in 1218. It is the oldest founded university in Spain and the third oldest university in the world in continuous operations. The formal title of 'University' was granted by King Alfonso X in 1254 and recognized by Pope Alexander IV in 1255.
Set of buildings that made up the university are situated around the square known as Patio de Escuelas. In this same square is the home of the Doctors of the Queen (15th century), whose façade is Gothic with Renaissance details and is now the Museum of Salamanca.

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.
