The cathedral gardens are on three sides of London's oldest Gothic church, completed in the 13th century after the original church burnt down. Much reduced in size from the original churchyard, the present garden was restored in 2001 and opened by Nelson Mandela, with Archbishop Desmond Tutu, who was a curate in the Southwark diocese. The East Churchyard herb garden was constructed around the ruins of the medieval Lady Chapel, using herbs which were grown in the Apothecaries' Garden of St Thomas' Hospital, originally near the site. The South Churchyard was designed using plants with Shakespearean and biblical resonance. There are good views from the river embankment to the north. Accessible toilet available.
