Solid church in granite built inside the medieval town walls. Work began in 1488 under the guidance of Biscay master Tomé de Tolosa, and using parts of a primitive Romanesque chapel (remains are visible in the north side); it pursued slowly, until the completion of the tower of the main façade in 1556. Important architects involved in the construction include João de Tolosa and Pero Galego. Inside, the building is a basilica with main nave and two aisles, and is notable for its inlaid ceiling (1565) showing oriental influences. The Mareantes Chapel, built by the corporation of seafarers, is one of the earliest renaissance works in Portugal. The church was classified as a National Monument on June 16, 1910.
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.
