St Pancras Lock is a lock on the Regent's Canal, in the London Borough of Camden. The St Pancras Basin is nearby. The Camley Street Natural Park is adjacent to the lock, on the down–, off–side. The eastern towpath is part of the Jubilee Greenway section 3. As the canal proceeds east, it passes over the railway lines into Kings Cross station; in 1939, stop locks were installed either side of the railway; to limit damage in the event of bombing. The nearest London Underground station is Kings Cross St. Pancras. London King's Cross and London St. Pancras are also National Rail stations.
