The Lambeth Walk is not as billed in the song. Quite a bleak but somehow beautiful mishmash of architectural accident–or–design; a legacy of stray WWII bombs intended for more auspicious near-at-hand targets, such as the Houses of Parliament. I study sculpture here each Monday; a lovely workshop inside. The exterior features one of only a few examples of an outside pulpit, apparently for the minister to take his message direct to the shoppers, in the Walk's heyday.

Half a mile from Markfield Park down the River Lee is Springfield Park. The park rises steeply up from the river and has an amazing array of tree species making it beautiful in all seasons. At the brim of the hill there is a line of park benches each one surrounded by box hedge offering a private view across the Lee Valley, Walthamstow and beyond. The park warden was nice enough to give me a chestnut log a couple of years ago from which I carved a bench and two stools.

Inspired by Dave Eggers’ projects in the USA such as the Pirate Store in San Francisco and Superhero store in Brooklyn, The Monster Supplies Store in Hoxton is home to the Ministry of Stories: A volunteer run organization, founded by Nick Hornby, to help young people with creative writing of all kinds through workshops and free mentoring sessions. The store is the “Purveyor of quality goods for monsters of every kind” with fascinating bottles and tins containing everything from eyeballs to Zadie Smith’s short story Mortal Terror.

To understand our 20th century

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.
