The Serpentine Galleries are two contemporary art galleries in Kensington Gardens, Westminster, Greater London. Recently rebranded to just Serpentine, the organisation is split across Serpentine South, previously known as the Serpentine Gallery, and Serpentine North, previously known as the Sackler Gallery. The gallery spaces are within five minutes' walk of each other, linked by the bridge over the Serpentine Lake from which the galleries get their names. Their exhibitions, architecture, education and public programmes attract up to 1.2 million visitors a year. Admission to both galleries is free. The CEO is Bettina Korek, and the artistic director Hans Ulrich Obrist.
