The octagonal chimney of the former Prince's Dock Hydraulic Pumping Station on the south bank of the Clyde in Glasgow. It's shape and the decorative freize around the top appear to be based on the Tower of the Winds in the Roman Agora in Athens, which dates back to at least 50 BC. The chimney was originally 172 feet tall, but was cut down to just 55 feet in 1927.
