Go ahead! Take it to the Bridge!

Another beautiful day, so I pumped the tyres up on my bike & cycled over to Chiswick to have a browse of the books in the charity shops there. It's not exactly a long ride, but I'm not what could be described as a natural athlete, so I shall be taking it easy for the rest of the day!
In search of a blip I then swung by Chiswick House gardens. Considered the birthplace of the English Landscape movement, the gardens have recently been extensively resored.
Bollo Brook originally marked the boundary of the gardens, but when they were expanded a lake was created, under which the brook now runs in a pipe! This bridge was built on the lake in 1714.
