Description
The Broadwood Folly at Juniper Hall is a landscape garden feature built around 1815, with the architect remaining unknown. This circular tower is made of regular courses of flint and stands approximately 8 meters high, featuring a decorative machicolated course at the parapet level. On the east side, there is a door that has been roughly blocked with flint, and a narrower entrance to the north is also blocked. At ground level on the southwest side, there is a small window opening, and at the upper level, there are four more openings—two large and two small.
Inside, the tower is rendered or plastered, and the settings for the steps of a spiral stair can be seen leading to the top. It appears there were two floors, one about 2.5 meters above the ground and another at the parapet level. A holme oak tree now grows through the center of the tower, with its leafy crown extending over the top.
The Folly was constructed by Thomas Broadwood, a member of the famous piano manufacturing family, after he purchased Juniper Hall in 1815. According to Headley and Meulenkamp, the tower was built as a memorial to Waterloo. Originally, there was a vista from the tower to the north through an avenue of beeches that led to Juniper Hall. Although the beeches were lost in a gale in 1987, the avenue is currently being restored as of 2005. The Broadwood Folly is listed as a substantially complete late-Georgian landscape feature that retains its context as an eye-catcher within the estate of Juniper Hall.
