A recent winner of the World’s Most Prestigious Conference Venue award, the impressive four-domed One Great George Street benefited from an extensive refurb in 2016. Just off Parliament Square, the venue has been upgraded internally and the external stonework has been deep-cleaned. In addition, the venue’s historic library has joined the existing event spaces. With oak panels, ornate ceilings and crystal chandeliers, the venue can accommodate both large conferences and more intimate functions. There’s also an in-house restaurant for 100 guests, with rooms available for private dining.
