Our room on first floor overlooked a private toll bridge and weir spanning the river that impounded water for the mill. The mill wheel still turns, but is no longer used for milling. Looking across the river about a hundred yards we could see a second mill on the opposite side of the bridge, and next to that, a floating pier where a ferry boat docks. From here it is only about three miles by ferry boat down the Avon to the town of Bath. We waited about an hour for the next ferry, really more of a motor-launch, and enjoyed the leisurely cruise down the river.
As we approached the town we passed under the main bridge across the river, one of only three in the world that has shops built on both sides of the bridge itself. The weir just downstream of the bridge is shaped like a deep, extended letter U, allowing at least three times the volume of water to flow over during flood stage as a straight-across weir.
During the Roman occupation of Britain engineers drove oak piles into the mud to provide a stable foundation and surrounded the spring with an irregular stone chamber lined with lead. In the 2nd century, the spring was enclosed within a wooden barrel-vaulted building, which housed the calidarium (hot bath), the tepidarium (warm bath), and frigidarium (cold bath). It was fascinating to wander through the different rooms and imagine what they must have been like so long ago.
