Bagacum (Today Bavay) was an Roman city and remarkable remains of ancient forum still exist. The 2,5 hectare are contains ruins of a central esplanade, temple and cryptoporticus (covered corridor or passageway).
The birth of Bavay after the conquest was the result of the reorganization of the territory by Augustus (probably between 16 BC and 13 BC). The town became the capital for the Nervii under the name of Bagacum and was an important junction of seven roads, the meeting-place of which was marked by a milestone, destroyed in the 17th century and replaced in the 19th century by a column.
From the Claudian period and especially under the Flavians in the late 1st century the city grew. Large monuments were built: a forum, thermal baths fed by an aqueduct bringing water from a fountain near Floursies located twenty kilometres away, and other buildings with a seemingly official nature adorned the city.
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.
