Defining Luxury in London

Formerly known as the Holy Trinity Church, the building was built in 1826, and boasts original designs from architect Sir John Soane. This building was first commissioned in 1818 by Parliament, after they set aside one million pounds to build this iconic building after the defeat of Napoleon Bonaparte. In 1936 this Grade II listed building was used by British publishing house, Penguin Books, who would use a children’s slide to deliver these books from the street to the secret crypt underneath the church. In 2006, One Events started operating from the Holy Trinity Church, which then became known as One Marylebone.

Both the interior and exteriors of this luxury wedding venue located in London make for the perfect wedding photos. Soane’s original architecture echoes neo classical antiquity and references the work of Italian architect Andrea Palladio. With delicate detailing, clean lines and an exceptional use of light, this luxury event space is arguably one of England’s finest portrayals of the neo classical style.

Choosing to host your wedding or party at One Marylebone will surpass every single expectation. With our luxury event planners here Scarlet on board to design your perfect wedding or corporate event and take care of your guests, there will be nothing left for you to do but enjoy yourself. 

Luxurious Venue in the Heart of London

The main room, ‘Soane Hall’ is the pièce de résistance of the venue. With the ceiling standing 27 feet high, at the end of which stands a stunning arch and a grand dome encompassing beautiful stained glass windows and incredible mosaics. A recent renovation saw the inner walls along the sides of the Soane Hall removed, meaning this breath-taking hall can now seat up to 350 people - perfect for the large traditional wedding celebration or party of your dreams.
