1 ALDWYCH UNDERGROUND STATION, LONDON: Built in 1907 on the site of the Royal Strand Theatre and used as an air raid shelter during World War II, Aldwych tube station closed down in 1994 and is now a well-known location for filming.
Preserved with many of its original features, including its booking office, telephone boxes and atmospheric signs, the station caters for up to 300 for events.
'The bizarre setting allowed us to create an element of surprise and mystery,' says Biss Lancaster account manager Emma-Jo Aldridge, who organised an event for 20 mixologists on behalf of cocktail drink firm Xante.
2 DALI UNIVERSE, LONDON: A 'surreal fantasyland' in the heart of London, the Dali Universe art gallery is inspired by the charismatic style and flair of Spanish sculptor and painter Salvador Dali.
Over 500 of his works are on exhibit, including the 'Mae West Lips' sofa.
The venue, which holds up to 800 for a cocktail reception and 300 for a sit-down dinner, can organise gallery talks, entertainment by flamenco dancers and Spanish musicians and food served by waiters with Dali-esque moustaches.
'Putting the Dali Universe on our invitations helped secure attendees and the gallery was a good talking point,' says CHA director Adrian Linden, who used the venue for a 300-strong agency corporate hospitality event.
3 FORT WIDLEY, PORTSMOUTH: In 1858, Napoleon III made preparations to invade England. In 1861, Fort Widley was built to stop him.

Outside, the fortress holds around 2,500 guests, and medieval archery, hog roasts and tours of its underground tunnels can be arranged.

Up to 100 guests can be welcomed by staff, given a private tour of the house and enjoy 18th Century music recitals and dancing.
'It is a small and intimate venue that enables people to talk about very confidential subjects,' says Great Circle Communications director Rachel Jones, who held a sit-down dinner at the house for a European think tank.

A former home of Henry VIII, the castle caters for parties of 20 to 500, but you can also take over the entire castle. Surrounded by a lake and 500 acres of parkland, it contains the world's only antique Dog Collar Museum.

7 LSO ST LUKE'S, LONDON: Ten minutes walk from the City of London, this 18th Century Grade I-listed Hawksmoor church was left roofless and derelict for more than 40 years until its restoration last year. Now a concert hall of the London Symphony Orchestra, St Luke's has established itself as a quirky venue for events. The church, which still has its original arched windows and vaulted ceilings, also has the latest hi-tech requirements and holds up to 350.
London Development Agency PR freelance Philippa Collins Robson chose the venue for an event for 150 people from financial firms because of its space and mix of old and new.

It can arrange for Welsh folk groups and musicians to entertain 120 to 150 guests and provide traditional Welsh dishes for dinners.

The atmosphere was noisy, exuberant and celebratory and achieved massive amounts of coverage, even in the diary sections of newspapers.'
