A few words about some of the photos toward the end of the video in that last post with video (from Dec. 28). Part of our walking tour (hey, there's a time and a place to roam free, and there's a time to listen to a guy who knows what he's taking about - some of those things are pretty amazing) involved the Thames Tunnel built by Isambard Kingdom Brunel, along with his father Marc Brunel (who actually started the project, came up with the original designs, and whom some claim was the more talented engineer, though history has showered more acclaim on the fils than on the pêre).
The tunnel was not accessible to horse and carriage, so they limited it to foot traffic, and it officially opened in 1843 (about 15 years behind schedule). Economically meh, culturally fascinating. Kiosks opened in the archways, and this place became the place to be - 2 million visitors in its first year, global acclaim as the '8th Wonder of the World,' a bustling, thriving thoroughfare under the Thames. Shops, food, performers, "Fancy Fairs," scientific demonstrations, a vital marketplace and meeting place.
And in 2010, they reopened the caisson to guided visits (you need to grab a rail, clamber down, stepping carefully, pivot round, duck down for a 6-foot long walk through a 4-foot high mini-tunnel before descending the staircase to the open area, but it is open).
And, as chance would have it, they also floodlight the tunnel on Sundays in November. And we just happened to be there in November, and just happened to be staying in Wapping, near the north end of the tunnel. [Ok, ok; those are a couple of the reasons we chose, against anyone's educated guess, to spend part of an afternoon on a walk devoted to Rotherhithe, Bermondsey, and this feat of engineering, rather than on things we would have found interesting on our own.] So we went back to the Overground station (they call it an Overground line, although this stretch of it is clearly underground and, rather famously, under the river. People also drive on the parkway and park in the driveway) and got those couple of shots of this 8th Wonder of the World.
There you have it. More about a tunnel than I ever thought I would write. I'll post our final London video soon...
