And in Islington and Hackney, nearly 90 of the most intriguing constructions in the boroughs fling open their doors to the curious crowds. Here are some of the highlights.

n The Museum of the Order of St John, in St John’s Gate, Finsbury, dates back to 1504, with the crypt of the priory church dating all the way back to the 1140s. It was the former home of the Knights of St John – a group of monks who gave medical aid to pilgrims in Jerusalem and took a military role after crusaders took the city. Today, their name is used by the St John ambulance service.
