8 Northumberland Avenue, a stones' throw from Trafalgar Square, is London's most central Grade II listed venue. Following lots of hard work and sympathetic restoration, English Heritage describes our Ballroom as ‘the grandest example of a Victorian Ballroom in existence' and that's just one of the amazing spaces we have on offer. Grand staterooms combined with cutting-edge technology make this the perfect venue for up to 1,000 guests to be entertained in style.
