Set in Coram’s Fields, the seasonal Bloomsbury Big Top brings bags of character and well over 2,500sq m of event space to this leafy part of London each Christmas. Best suited to large-scale dinners and conferences, the venue has also catered for fashion shows and concerts. With capacity for over 1,000 guests, it’s one of the biggest event spaces in this part of town. Although effectively a temporary structure, the Big Top has all the sound, lighting and event facilities you’d expect from a permanent venue. It comes with a ceiling draped in pea-lights, a thermostat-controlled heating system, as well as carpets, luxury toilets and on-site catering facilities.
