Even some people who have lived in Leeds all their lives don't know that the City Train Station is built on a massive network of brick arches called The Dark Arches. Mostly built back in the 1860s, the network that supports the station used over 18,000,000 bricks and was a record for the time. The River Aire runs directly underneath through a set of four massive brick tunnels.
These days, the station is the busiest outside of London and most of the travellers are blissfully unaware of the amazing secrets that sit below their Costa Coffee and Blackberrys. The station handles an amazing 110,000 passengers a day.
Lots of The Dark Arches are now a business estate called Granry Wharf, this consists of shops, a few discos and bars and a big new hotel and "luxury apartment" complex. If you look (and crawl) further though, some bits haven't been used for over 120 years
Some of the system has total public access, I have included those bits as people outside of Leeds may not have seen them before. If you live in the area and have never been down here, I suggest you do so.
