Urban oddity of the week

As it's Halloween week, let's meet London's spookiest postbox. The Penfold-style pillar can be found in Walthamstow Village, on the corner of Church Lane and Orford Road. It is no longer used for collections, and instead seems to be the dwelling of some diminutive dead-eyed monster. The eerie scene is heightened by the surroundings. In the background looms Ancient House, which remains a private residence having stood here for almost 600 years. The stories it could tell! Not pictured, on account of being the other side of our lens, is the graveyard of St Mary's church. If ghosts really did exist, this would be spook central.

Good cause of the week

This week, we'd like to give a shout out to FoodCycle Wandsworth Road, the 15th FoodCycle project in London to give out free meals to those who need them. FoodCycle is also a virtuous cycle: it provides meals to families and individuals in need, but it also reduces food waste by only using surplus food that might otherwise have been binned. On top of that, each FoodCycle event offers a welcoming space to make new friends and have a bit of a chat. FoodCycle Wandsworth Road opens at Christ Church Community Hall on Union Grove in Lambeth on Friday 19 November with food served from 12.30pm. It then returns at the same time every Friday.

You can help in two ways. First, spread the word to anyone you know who could benefit from the initiative. Anyone can come to a FoodCycle meal — no need to fill out a form; you can just turn up. Second, the FoodCycle needs volunteers. Perhaps you help cook the food, act as a host, or pick up the food from local suppliers. Find out more on the FoodCycle website, along with details on similar initiatives in other parts of London and beyond.
