The Chelsea Physic Garden was established as the Apothecaries' Garden in London, England, in 1673 by the Worshipful Society of Apothecaries to grow plants to be used as medicines. This four acre physic garden, the term here referring to the science of healing, is among the oldest botanical gardens in Britain, after the University of Oxford Botanic Garden. Its rock garden is the oldest in Europe devoted to alpine plants and Mediterranean plants.
