SESH

12th Knot Rooftop Bar is a renowned nightlife destination situated atop the Sea Containers London, a stylish hotel on the vibrant South Bank at 20 Upper Ground, SE1 9PD. The venue opened as part of the significant 2014 transformation of the historic Sea Containers building—originally designed in the 1970s as offices and later reimagined into a contemporary riverside hotel and hospitality hub. 12th Knot, previously known as Rumpus Room, quickly established itself as one of London’s premier rooftop venues, lauded for its panoramic views of the Thames, St Paul’s Cathedral, and the iconic city skyline. With its plush interiors, floor-to-ceiling windows, and expansive terrace, the nightclub seamlessly fuses the spirit of a classic cocktail lounge with the energy of a vibrant bar, often drawing a sophisticated crowd of locals, creatives, and international visitors.

Its reputation has grown as an essential stop for those seeking sumptuous cocktails, live music, and an electric atmosphere, especially during sunset hours or late-night celebrations. Culturally, 12th Knot embodies the dynamism of modern London nightlife—blending music, design, and hospitality in a unique space that prioritizes both relaxation and revelry. While the venue has retained its original location at the top of Sea Containers London, it underwent a significant rebranding from Rumpus Room to 12th Knot in 2018, updating its décor and programming to reflect an even more diverse and adventurous spirit.

This transformation cemented its status as a go-to for cutting-edge music events and exclusive parties without sacrificing its commitment to spectacular hospitality and style. Notable artists who have performed at 12th Knot include internationally acclaimed DJs such as Jazzie B, Norman Jay MBE, and DJ Yoda, alongside celebrated local talents like Soho Radio’s Tonic Armstrong, and emerging UK acts frequently curated through partnerships with respected music collectives. The venue’s dynamic mix of established headliners and up-and-coming performers consistently draws music lovers eager to experience London nightlife at its most sophisticated and lively.
