One Marylebone formally Holy Trinity Church was built in 1826-28 to the designs of Sir John Soane to celebrate the defeat of Napoleon.

One Marylebone provides a glamorous and unique central London venue for the most exclusive private and corporate events in a number of stunning spaces and a large garden. The building was deconsecrated 50 years ago and returned to its former glory in 2007 opening its doors as London’s most exciting new events venue.
