I vaguely thought about leaving London recently and the British Library came to mind as somewhere I’d miss. It’s an essential resource because it has almost everything. It also has some interesting exhibitions.

Misty mornings on the river beat the rest... this pic was taken in February on the Walthamstow marshes.

Aside from the fact of the underground being the oldest running railway system in the world, I find the underground just an incredibly strange place. Sometimes it’s like I’ve entered an organised maze and just walk without even thinking. The photo is taken of the floor from one of the trains, it’s normally what you tend you look at when you’re on the train.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

Go check out this very untypical gallery in the underground. You don't need a ticket and it does only take you a second to soak in the art displayed.
