Northwick Chapter of the Royal Arch Masons was consecrated on 11th May 1938. It meets regularly three times a year on the fourth Tuesday in March (Installation), May and November. Members come from several craft lodges including Northwick Lodge 5020, Copse Wood Lodge 8000, and Middlesex Century Lodge 5837. The Chapter is a small very welcoming place too become involved in Royal Arch Masonry where
new members are made to feel completely at home from their very first meeting. Visitors are always welcome to come to the chapter and join in with the various ceremonies and the festive board afterwards. Much of the work of the chapter goes towards raising money for charity and the Chapter was made a Steward of the Middlesex RMBI Festival 2009. Charitable money is also given to local and national charities as required and includes recent donations to The British Ski Club for the disabled and St Lukes Hospice.
