About Venue
Unique. Out-of-the-box. Extra-ordinary. Welcome to The Mermaid London – the independent home of one-of-a-kind events, and the go-to venue for large-scale events in the City of London.
Five incredible event spaces and a capacity for nearly 2,000 delegates requires an expert team ... One that is dedicated? Yes. Experienced? Of course. Creative? Undoubtedly. Meticulous? It goes without saying. Passionate? Absolutely. All essential, and all characteristics that define The Mermaid London.
The Lower River Room is a contemporary London event space - trendy, flexible and designed with intimate to medium-sized gatherings in mind. Oh, and did we mention its sweeping views of London’s iconic skyline, overlooking sights including Tate Modern, Shakespeare’s Globe and The Shard? Yep, there’s that too.
Whether you’re planning a seated dinner, award ceremony, conference or product launch, let the Lower River Room exceed your expectations.
UNLOCK THE ULTIMATE EVENT EXPERIENCE
The Lower River Room can also be coupled with the Upper River Room and Queenhithe. This allows for larger events to take place – ideal for exclusive use.
You may choose to host a conference in the Upper River Room and Queenhithe and use the Lower River Room as a breakout area or drinks reception. Or why not use the Lower River Room for your intimate dinner and the Upper River Room as an exclusive private party space?
The large full-size windows boast panoramic views of London's iconic skyline, bringing the city of life to your event, as well as an abundance of natural daylight.
The room makes the perfect setting for meetings, smaller lunches, gala dinners and banquets, award ceremonies and drinks receptions. Its whitewashed blank canvas walls means you can dress the space any way you like, transforming the room to suit your taste and branding requirements.

Had our company's christmas event here. Spacious auditorium and backstage area where food & drink were served. Facilities were satisfactory and it is pretty easy to get to.

Theme didn’t match decorations in venue. All staff was great.

Quite easy to find. Accessible. 3 lifts. Decent toilets. Enjoyed my 2 day conference and training. From Blackfriars stn turn right then immediately right again. 60/80 Meters there's a small underpass

I have been here on a number of occasions for conferences. It's well equipped, things seem to run smoothly and provide everything that you would expect. The lunches are good and this time had gluten free options for mains, but not desert. The cookies at breaks looked delicious though no no gluten free choice, so I had to settle for healthy, fruit option. They really looked after my waistline! The staff are friendly and helpful.

The staff seemed to be intent on preventing delegates from doing things: e.g. "you can only have one type of food on your plate". Thankfully on the second day of the event this was no longer the policy. No coffee available at noon and nowhere to procure it on site (absolute showstopper for some of us).
