The herb hill
Although there are no ruins to be seen on Castle Hill, this grassy mound is of great importance in the history of Cambridge. This was the site of the Roman town of Duroliponte, originally an Iron Age hill fort.
It is worth climbing to the top of the Castle Mound as it offers an expansive view over the roof tops of the town and surrounding countryside. On a clear day it is possible to see Ely Cathedral to the north.
