The Museum of the Order of St John tells a unique and fascinating story — the story of the Order of St John — from its origins in eleventh century Jerusalem, through to its role today with St John Ambulance and the St John Eye Hospital in Jerusalem.

This story highlights how, from founding a hospital to care for sick pilgrims in eleventh century Jerusalem, St John has maintained its caring role to the present day, working on numerous humanitarian projects worldwide.

The Museum occupies two sites in Clerkenwell: St John’s Gate, which dates from 1504; and the Priory Church of St John with its surviving twelfth century Crypt.

What our visitors think

A very enjoyable tour. The guides were marvellous and knew what they were talking about. Look forward to another visit.

The Museum has a fabulous, well organised display; historic and clear, enjoyable to see.

April’s 10 Minute Talk

Issues of connoisseurship, authentication and attribution have been of particular interest to the Museum recently. "The Cardsharps" by Caravaggio, kindly loaned to the Museum from a private collection, has been the subject of a legal argument concerning alleged negligence and the duty of care owed by the auction house to the vendor.

"The Cardsharps" is a much copied painting, and Caravaggio is known to have replicated his own works. Attribution is never an exact science, and it is not uncommon for paintings to move from the status of copy, to the hand of the master, or indeed vice versa.

The Museum displays "The Cardsharps" as by Caravaggio, based on the considerable scholarship of Sir Denis Mahon who discovered the work, and this opinion is supported by other academics who, like Prof Mina Gregori, spent more than half a century studying the Artist. Others may argue, and indeed they have, that it is a very fine copy.

Come and listen to our Curator’s short talk before viewing the painting and deciding for yourself!
