Middlesex Day is celebrated each year on 16th May. Middlesex Day, as with most county day celebrations, has been growing in popularity year on year. 2022 has unquestionably been the biggest event yet with even the Prime Minister (MP for Uxbridge and South Ruislip) joining in. We present here some highlights from the day. Huge credit goes to County of Middlesex Heritage for making it happen. Our Portrait of Middlesex gives an overview of some of the highlights of our most populous county.
