After a few years of not going to any open house events, we had a few we wanted to visit this year. As usual we had zero luck in any of the big attraction ballots.
Then the weather hit. Basically yesterday (Saturday) and today were just too hot to wander around London.
Yesterday we visited the union chapel in Islington, and attempted to find a cool breeze down by the Thames at the river police HQ (which was closed).
Today, we visited a beam engine that Open House said was in steam (it wasn’t) but not being in steam meant we got a good tour on top of the engine, and down below where the sewage pumps live.
