Live Jazz and Blues outside the Lamb in Leadenhall Market provided by www.cityplay.co.uk Leadenhall Market is a hive of activity throughout the year. This year we have had some fantastic events in the spectacular covered market, St Georges Week in April, Sax in the City in July, and the Leadenhall Fair in September. We hope you will join us throughout December for your festive celebrations and the Lord Mayors public party when we switch on the lights.
