Nash Conservatory at Kew

This beautiful 19th-century glasshouse at Kew has floor-to-ceiling windows and is one of the oldest in the gardens. Originally built in the grounds of Buckingham Palace and then moved to Kew in 1836, the conservatory is a bright, unique space available for parties of up to 200 people. Guests can also spill out on to the adjoining lawn if the weather allows.

Address Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AE.
