A new Era

London nightlife is constantly evolving, but some experiences are defined by something deeper than a dancefloor, a DJ booth or a spectacular venue. The Mansion London has always been about creating a world for one night, a place where music, people, art and unexpected encounters come together. Now, that world is entering a new chapter, with a fresh musical direction under the curation of Oinimod. This isn't simply Halloween in London. If you're looking for the party where music, extravaganza and people collide, this is the night to be part of.
