Crypt is known for one spectacular feature alone. Access could not be simpler, the shiny new hinged easylift manhole drops directly in this feature. It's literal drain tourism with none of the hard work usually needed to see something so impressive. The turbulence below is clearly audible as you approach the manhole, as the manhole lifts open it roars over the street.

An oviform and a round tunnel enter the chamber from upstream, and drop into a central channel which collects the flow and directs it downwards into a lower level tunnel. Spanning the channel and dividing the chamber are rows of two tone brick columns which arch into the ceiling. The chamber seems far more elaborate than it needs to be, why not simply merge two tunnels through a series of churnblocks?

Was it simply  pride in their workmanship and professionalism that inspired such an attention to detail in a place so few would ever see? This chamber is elaborate in ways totally unnecessary. Chamfered edges, rounded edges, dual manhole access, safety handrails, the dominating brick columns. It's over the top and excessive but who's to complain.



The volume of water collecting in the channel makes passing into the lower level tunnel a dangerous looking affair, visibility is low and ending up a soaked rat is guaranteed. There is manhole access further downstream of the tunnel, which leads back up to a neat staircase closer to the chamber. Downstream of the lower manhole remains unexplored, and upstream from the chamber showed no features or changes after 10 minutes of struggling against the flow.
