Reopened after a £3.7 million refurbishment, this is three museums in one. The first shows the history of St John’s Gate: built in 1504 as the south entrance to the Priory of the Knights of St John, it’s also been a coffeehouse, owned by Hogarth’s family, and a tavern. In the eighteenth century it was a printing house for Gentleman’s Magazine. The second part of the museum concentrates on the Order of St John, founded in Jerusalem in 1099. Armoury and regalia are on display, as well as exhibits showing the Order’s devotion to nursing. The third and final part is an interactive display on the Order’s modern incarnation – the St John’s Ambulance. Make sure you see the 1785 version of ‘The Dictionary’ by one Samuel Johnson.
