The Co-Cathedral of St. Nicholas was built between 1613 and 1662. It was designed between 1610 and 1615 by Agustín Bernardino, a student of Juan de Herrera, and was constructed over an ancient mosque. The older cloister was built originally in the 15th century in Valencian Gothic style.
The cathedral has a Latin cross plan, though the transepts are quite short. Flanking the nave are six interconnecting side chapels and an ambulatory around the apse. A blue dome rises 45 meters above the crossing. The chapel of Holy Communion, configured as a small Greek cross-planned temple, is considered to be one of the most beautiful examples of the Spanish Baroque.
The external appearance of the cathedral is quite sober. The main facade located on the east side is of the Doric order, and the one built on the south side is of Ionic order.
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.
