Visit "the Garden" the centre of London’s jewellery trade, learn what "Findings" are, and the days rate on gold and silver , and small shops where they sell gemstones at reasonable prices, we will also visit the Goldsmiths Centre where young jewellers are taught to become masters of the craft , after taking a moment of rest at the hidden St Ethelreda's C11th chapel , once part of the Palace of the Bishop of Ely . Then on to Farringdon with a walk through Smithfield Market , to learn about its unusual history , and a visit to see St John's Gate museum , near the home of St John’s Ambulance, whose first brothers were Knight Templars. After their dissolution in the Tudor period, the Master of the Revels, who licensed all Theatre production there , had many visits from a certain Will Shakespeare , to check there was no treasonous content in his work !
