Can you identify where in London this picture was taken? If you think you can, leave a comment below. We’ll reveal the answer early next week. Good luck!

If you’ve been living in suspense for the past couple of weeks, then you need wait no longer. This coffin-shaped object is actually an interactive musical artwork commemorating clown Joseph Grimaldi (1776-1837), credited as the father of modern clowning, and the man remembered in the annual clown service held at Holy Trinity Church in Hackney each February. The artwork (and another next to it dedicated to theatre proprietor Charles Dibdin the Younger) was created by Henry Krokatsis and is located in Joseph Grimaldi Park on Pentonville Road in Clerkenwell – the site of the churchyard of the former Pentonville Chapel. The memorial is actually located on the site of Grimaldi’s grave (the gravestone has been moved and now stands nearby) and is tuned so that his popular song Hot Codlins can be played by standing on it.
