Heritage Open Day: Annual Open Day for anyone interested in the building and what goes on there. 'Meet a Freemason!' The Freemason's Hall is usually closed to the public, but on this occasion we open the doors and allow anyone to come in and have a good look around. Freemasons are on hand to ask questions and guide visitors around the building. Refreshments are available and the whole day is a relaxed way to find out more about the Hall and Freemasonry in the UK. There are no set times, just turn up and be assured of a warm welcome, plenty of free parking available on site.
