The service also sees the lighting of a candle for any modern clowns who have passed away over the past year, and has taken place at Holy Trinity since St James's Chapel on Pentonville Road, where Grimaldi is buried, closed in the 1950s. The site of his grave is now called Joseph Grimaldi Park.
We are told that, after the service, visitors can also take time to examine the remaining collection of clowning memorabilia which is held at the church since Clowns Internationals’ Gallery/Museum moved from All Saints to Wookey Hole Caves in Somerset, and this includes the 'egg register', on which clowns' face-paints are officially recorded on eggs.
The service begins at 3pm, but you should arrive by 2pm. For more, see the Clowns International website.
