Becket's Well. This structure was erected in 1843 over a spring outside the old town walls. This is the spring at which it is reputed Thomas A Becket rested and drank on his flight from Northampton Castle after his trial in 1164 for "defiance of royal authority". Becket escaped to Flanders before the verdict was brought in, but returned to England after six years. He was murdered in Canterbury Cathedral in 1170.
