Hey, I'm quite into the topic of sewer systems exploration (especially the older, historical ones) for a few years now, and this is the first time I'm seeing a question like yours, so I feel obliged to share all the sources I have found. general disclaimer: following sources are in various languages, but I'm still including them, since the videos don't have much talking in them, and you can easily translate blog sources. 1) Youtube: I know both Kanalismus35 and valdigger, and they are both the best, most in-depth as well as possibly the only real Youtubers in the sewers topic. However, there are at least a few more: - https://www.youtube.com/@zemi02 https://www.youtube.com/@zemi02 - yet another creator from Czechia, Brno exploring bits and pieces of the sewer infrastructure, maybe not so refined as @kanalismus35 but worth checking out as well - https://www.youtube.com/@KanalVision https://www.youtube.com/@KanalVision - from Germany, not much context or inisght given but still nice shots of huge sewers - https://www.youtube.com/@penetratorscavenger/ https://www.youtube.com/@penetratorscavenger/ - from Poland, Warsaw, they do urbex in general, but also go deep into historical sewers in Warsaw. Examples: https://www.youtube.com/watch?v=SGcou71yKoU https://www.youtube.com/watch?v=SGcou71yKoU https://www.youtube.com/watch?v=rVOVmXZLE6c https://www.youtube.com/watch?v=rVOVmXZLE6c https://www.youtube.com/watch?v=oZJ0L3DPAFc https://www.youtube.com/watch?v=oZJ0L3DPAFc 2) Websites/blogs - https://guerrillaexploring.webador.co.uk/content/draining https://guerrillaexploring.webador.co.uk/content/draining - from England, London, incredibly in-depth context, knowledge and exploration of legendary London sewers - an absolute must read & see if you are into the topic - https://penetratorscavengerteam.blogspot.com/search/label/kanały https://penetratorscavengerteam.blogspot.com/search/label/ka... - from Poland, Warsaw, already mentioned before, they have much more thorough and in-depth content about Warsaw sweres with tons of photos on their blog than on yt. Just install a web page translation browser extension and you are good to go - https://www.sub-urban.com https://www.sub-urban.com - specifically about London, also a great, in-depth source - https://www.28dayslater.co.uk/forum/uk-draining-forum.94/ https://www.28dayslater.co.uk/forum/uk-draining-forum.94/ of course this one for all of UK Summing up, I know I went quite a bit off-topic here, but I hope I helped a bit regarding youtube sources as well. Also happy to get to know any other Youtubers doing some proper exploration.
