The living wall

Rue-leaved saxifrage

Rue-leaved saxifrage - one of the wall's native species

Our friends at Colchester Natural History Society have long known that, as well as being a unique ancient monument, the wall is also a nationally important botanical site. With its 2000 year history, the wall has become a unique habitatĀ for plants of many kinds, including rare lichens, mosses and flowering plants.

The brickwork is covered with mosses and lichens but look, in particular, for the small Black Spleenwort fern and the scarce Rue-Leaved Saxifrage (pictured left) in early Spring on the Roman Wall between upper and lower Castle Park.
