Huxter Fort is an iron age fortification on the island of Whalsay. It is on an islet in the Loch of Huxter, connected to the shore by a causeway. The fort was probably built around 300 BC, the generally accepted date of most similar fortifications in the region. This ring fort and blockhouse existed before the other two forts in Whalsay, brochs that were built just before the Christian era started. Huxter was standing until the 19th century. When described in 1879, the fort was much less dilapidated than today.
Entry to the fort enclosure was across the causeway, then through a passageway with rooms on either side and with a doorway in the center. The entrance section is part of the main wall. This is similar to the blockhouse at Clickhimin. The passage is just 0.76 m wide at its opening, and 1.1 m at its inner end. It has been conjectured that there may have been a two-story timber building built against the inner face of the fort. There is little structural evidence for this today. However, early accounts of the fort indicate that this may have been the case, and other forts show traces of what may have been internal stairways.
A ring wall runs around the islet, with a two-room blockhouse forming the defense opposite the causeway. The ring wall seems to have been built separately from the main structure. The blockhouse forms part of the ringwork, but is not bonded into the ring wall. The weaknesses in the defense of this and related structures could be explained by additional defenses of wood and thorn branches that have disappeared without leaving any trace. Another possibility is that the defenses were mainly symbolic, and perhaps played a part in warfare that was conducted according to formal rituals.
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.
