In 1805 the Grand Unicon canal from London to Braunston opened, passing through Fenny Stratford. To overcome a local problem during construction a temporary lock was installed here at Fenny Stratford and still remains to this day. There is a pub here namely the Red Lion public house and the lock keeper's house still stands and adds a tad of historic ambience to the place.
