One Marylebone London Events

Set on an island in the middle of Marylebone near Regent’s Park, One Marylebone is a striking Holy Trinity Church that has stood the test of time. English Heritage has protected it as a Grade I listed building, and its current owners transformed the early 19th-century structure into a historic landmark venue for all kinds of events. 

Designed by one of England’s most acclaimed Neoclassical architects, Sir John Soane, One Marylebone is a work of art. Inside, the primary event space is called Soane Hall after its creator. Its high ceilings, original altar and spectacular stained glass windows make it an incredible setting for corporate events, parties and weddings.

Upstairs, the bright and airy Galleries contrast with the historic setting on the ground floor. These modern elongated event spaces lend themselves to wedding ceremonies, fashion shows and stylish drinks receptions. The combination of pared-back wooden floors and white walls allows you to put your stamp on the set of spaces. 

With their expert team of in-house Event Planners also on hand to help, your One Marylebone event will run without a hitch. 

Highlights of One Marylebone London Events:

  • Venue hire until midnight with the option to extend until 3am
  • Striking 27 metre high ceilings for a dramatic event aesthetic
  • Original mosaics, stained glass windows and altar still intact
