One of those “I never knew that” moments as I was rushing over London Bridge towards the tube station and going around the spike I dodged two stone plinths that people normally sit on.
Out of the corner of my eye though, for the first time, I noticed a small metal plaque with text on it, and being the curious sort, stopped to read it.
Turns out these two otherwise unremarkable stone seats are actually remnants of the old London Bridge. Not the really old medieval bridge, but the 1825 replacement which was itself taken down in 1967 and sold to the Americans.
According to the metal sign, these are two granite coping stones from the bridge and were left behind, as was quite a bit of the abutments, which are now incorporated into the fabric of the modern bridge.
So, if like me you are hurrying past one day, stop to pause a moment at an overlooked bit of London heritage that is hidden in plain sight – and if with friends, point it out to them as an example of your superior London knowledge.
