Celebrating Luxury in London

One Marylebone (formerly known as the Holy Trinity Church) was built in 1826 and boasts original designs from English 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 French Military leader Napoleon Bonaparte.


With a rich history in literature, this venue is perfect for those who have a passion for creativity and the English language. The British publishing house, Penguin Books, managed the building in 1936, Penguin Books used to store their books in this Grade II listed building, and they used a children’s slide to deliver these books from the street to the crypt underneath the church. In 2006, One event started operating from the Holy Trinity Church, which then became known as One Marylebone.

Both the interior and exterior of this luxury wedding venue located in London make for the perfect wedding photos. Soane’s original architecture echoes Vitruvian principles, neo-classical antiquity and references the work of Italian architect Andrea Palladio. With delicate detailing, clean lines and exceptional use of light, this luxury event space is arguably one of England’s finest portrayals of the neoclassical style that found inspiration in the ancient Greeks and Romans.

Choosing to host your destination wedding or party at the crown of One Marylebone in London will surpass every single one of your expectations. Whether it is the rich history dripping from every crevice of this stunning building or the grand decor, you will be sure to have an experience you didn’t even think was possible.

With luxury event planners Scarlet on board to design your perfect wedding, whether a traditional or cultural one, and take care of your guests, there will be nothing left for you to do but enjoy yourself.

Soane Hall is the pièce de résistance of the venue, with the ceiling standing 27 feet high, and the room enveloped in beautiful stained-glass windows and incredible mosaics.
