The building of Hultaby Castle was begun in the second half of the 13th century and it was inhabited in the middle of the 14th century by the Swedish councillor of the realm and earl of the Orkney Islands, Erengisle Sunesson (Bååt).
Together with the castle itself, which is 28 by 32 metres, the castle area consists of a group of 10 building foundations, which lie in an L-formation on the southern and eastern sides of the castle. There used to be an additional fifteen or so buildings spread out outside the castle area. The upper part of the castle, which consisted of a great room, two minor rooms and a tower, and the surrounding buildings, were of timber.
The castle is thought to have been burnt by Count Henrik of Holstein (known as “Järn Henrik”, Iron Henrik), the bailiff of King Albrecht, during the 1360s, at which time there was civil strife between the rival Swedish kings Magnus Eriksson and Albrecht of Mecklenburg.
The area around the old ruins shows many traces of the old cultivated landscape. Apart from the mounds of stones left by the farming of times past, there also remain plants that are favoured by hay making and grazing, such as leopard’s bane, greater yellow-rattle and common milkwort.
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.
