Euston “Arch” Stones
As British Waterways was planning the construction of Three Mills Lock in Prescott Channel, various sources mentioned that remains of the Euston Arch were thought to be in the vicinity. It used to mark the entrance to the 1833 Euston Station, but was demolished in 1962 despite a massive public outcry. A few stones were found during the work to the lock and some more will be retrieved shortly under the eager eye of Dan Cruickshank, representing the Euston Arch Trust and English Heritage.

Danger UXB
An unexploded bomb was found on 2 June 2008 in the Prescott Channel during the works to build a new lock. The whole of the Three Mills area had to be immediatly evacuated. The Bomb Disposal Squad, the Royal Engineers, worked around the clock over the next five days to deal with the threat, successfully we are glad to say.
