This site is located under the Great Northern and was originally an old canal which was drained to make way for air raid shelters during the Second World War. After the success of our over underground Manchester trip we decided to head towards the great northern warehouse a few weeks later only for a reccee but we managed to get lucky. Access was through a tiny hatch on a underground car park and down a 30 foot ladder. After spending around 45mins under here we decided to head back to ground level as our lack of preparation and lack of torch batteries got the better of us. Sadly our return trips never ended up with another success due to the proximity of the entry to security guards and security cameras.
