- Location description
- The River Ravensbourne is a tributary of the River Thames, flowing for 17km from its spring in Keston, London Borough of Bromley, to its confluence with the Thames at Deptford. The area around the Ravensbourne is mainly urban and residential. However, it does flow through some greenspaces, including Church House Gardens in Bromley where Glassmill Pond is located. This historic millpond is one of the oldest features in Bromley, associated with one of 11 mills on the Ravensbourne mentioned in the Doomsday Book. Therefore, it holds great heritage value within the area.Originally, Glassmill Pond and the River Ravensbourne were separate waterbodies. However, in 1955 the river was diverted to flow through Glassmill Pond with the aid of two weirs at the inflow and outflow points. While this offered good news at the time, the connection initiative between Glassmill Pond and the River Ravensbourne has also brought some challenges such as flood risk and barriers for wildlife to thrive.
