London's oldest botanic garden, the Chelsea Physic Garden was first established in 1673 by the Worshipful Society of Apothecaries as a teaching garden, designed to allow apprentices a structured environment in which they could learn to identify important medicinal plants.
Today the garden is home to about 5,000 edible, medicinal and healing plants.
A statue of the garden's benefactor, the Irish physician and collector Sir Hans Sloane, sits in the garden. Sloane also contributed to the founding of the British Museum and the Natural History Museum, as well as contributed a small collection of rare religious works now held in the chained library at Chelsea Old Church, where he is buried.
A self-guided historical walk is plotted out at the garden to highlight some of the key personalities involved in the garden's history, including the exploring naturalist Sir Joseph Banks.
