Bothwellhaugh Roman Fort

Bothwellhaugh Roman Fort, known as Clotagenium ("Clyde-mouth") to the Romans is the remains of a Roman legionary fort in North Lanarkshire near Glasgow.

It was built as part of the western side of the Antonine Wall built around 142 CE. A comparable eastern site would be Inveresk Roman Fort. The forts defenses consisted of a turf and clay rampart 23+1/2 ft thick, supported on thick sandstone foundation slabs, part of which was preserved to a height of around 5 ft. A 33 ft wide berm separated the fort wall and the first of two ditches, each measuring about 15 ft wide and 4 ft deep, and spaced 7 ft apart. It was built in a rhomboid pattern and was large enough to house both troops and cavalry. A number of artifacts were taken from the excavations on the site, such as a carved drain cover, to the Hunterian Museum at Glasgow University and are now on show there.

Near the fort are the well preserved remains of a Roman Bath house and a medieval copy of an original Roman Bridge over the South Calder Water. The distance from the thermae (baths) to the fort suggests there are other, as yet undiscovered structures.
