San Gregorio is a former church founded in the 9th century and, in the 13th century, it became a Benedictine abbey. In the mid-15th century it was rebuilt to the current appearance under design by Antonio da Cremona. In 1775, after a long period of crisis, the monastery was closed and in 1807, after the Napoleonic occupation of Italy, also the parish church was suppressed. Deconsecrated, it was converted in a mint laboratory and then an art restoration center. It is now closed and not used.
It has a Gothic exterior with an ogival portal, elongated mullioned windows with ogival top, and apse.
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.
