The hotel we stayed at in Bradford-on-Avon was right beside the Kennet and Avon Canal:-

Canal lock at Bradford-on-Avon:-

In operation:-

This was once the lockkeeper’s house:-

We took a stroll along the canal and came upon a World War 2 pillbox:-

This small blue plaque on the pillbox states it was once part of a stop line which in case of invasion was intended to prevent German troops crossing the canal:-
