How can this be underneath a city ?

How can this fit underneath a city. Its a massive river culvert. In this video we take a journey to Sheffield in the UK. We are going to look at a fantastic storm drain that is locally known as Megatron. We initially follow the Porterbrook to its confluence with the River Sheaf the very river that gave Sheffield its name. This confluence is found under the main Sheffield Midland Railway station. We follow the river Sheaf until it gets to the mighty Megatron chamber. A huge underground chamber that is a brick built victorian arch designed to carry trams across the river sheaf above ground back in the late 19th century Victorian times. Megatron is a victorian storm drain designed to carry the flood waters of the River Sheaf and the Porterbrook safely out underground Sheffield to the River Don. Lots of walking in old Victorian river culverts in waders. This is an underground urbex in Victorian brick built river culverts hidden underground in the city of Sheffield UK

Hi Martin, great to see you on this side of the pennines in my old stomping ground, you did well to explore it in one go. I spent several days down there, going a bit further each visit, and remembering all the deep pools and slippy bits as I spent hours light painting, trying to get the perfect photograph Still unbelievable that this magnificent structure lies hidden under the streets of Sheffield, and thanks for giving me a mention, appreciate that, all the best with your future explores.....Pat

[@MartinZero]

Hello Pat great to hear from you. Yes this was very much inspired by you and your videos. I think you did a better job as you got in the other end as well and had a boat. Also love your light painting, great results. We just took a few snaps. All the best Martin 👍🏼

Hi Martin, when I was visiting family in Sheffield Mid 2018 I heard a rumour that a forgotten castle had been discovered in Sheffield and was starting to be unearthed. I heard this at the end of my trip before I left to head home to Australia so I never had the chance to look into it further. I think I heard it was discovered under an old market place. Might be a good thing to look into on your next trip to Sheffield, I won't be able to get back for some years due to this pandemic so I'd love to know how far along the excavations have got.

[@jvanhee71]

Perhaps that was it at the end. The old stone section is directly beneath ‘Castle-Ford-Market’.

[@jordyboy62]

I live in Sheffield and it is known that there used to be a castle in Sheffield somewhere in the Castfield area but it isn't known exactly where as there doesn't seem to be any evidence of it left but there are paintings, maps and documents to prove it did once exist. My old office is build on the site of the old Castlefield markets where it's thought to have been but nothing was found.

I watched Ant’s release of this a couple of days ago and now yours. They compliment each other well as you each have your own presentational and historical styles.

Great video, I live opposite pocket park and have always wanted to walk this route. One thing I’ve always pondered is the reasoning behind the deep channel section that runs through the Porter brook for a great length in the area around where you entered. Any ideas? My thought is that it was to ensure a higher flow during low rain season to wash away any toxic or foul water that would otherwise start to smell if flowing slowly?
