Roman Bath House Bearsden

The first known settlement on the site of present-day Bearsden was a 2.5 acre (10,000 m²) Roman fort in the second century AD. Between 142 and 144 AD, under Emperor Antoninus Pius, the Romans built a stone and turf fortification, called the Antonine Wall, between the Firth of Clyde and the Firth of Forth. They also built the Military Way, a road that ran parallel to the south of the wall. They built the aforementioned fort at the intersection of the Military Way, and the north-south road from Glasgow to Loch Lomond. In 164 AD, after only 20 years, the Romans withdrew to Hadrian's Wall.

Little of the fort remains to be seen today. However, close to the fort was a Roman bath-house, built in approximately 142–143 AD. The bath-house's remains were discovered by builders digging foundations for a housing development in 1973. The site was donated to the government, and today the remains lie well-preserved 150 metres from the town centre.

Two further stretches of the Antonine Wall's stone base can be seen in the New Kilpatrick cemetery on Boclair Road.
