This is a commemorative lapel pin for Hornsey Lodge No. 890, which is a Freemasons' lodge operating under the United Grand Lodge of England (UGLE). It was produced to mark the lodge's 150th Anniversary on 7 December 2011 (indicating the lodge was originally warranted or consecrated in 1861). The design features an enamel illustration of St Mary's Tower (the landmark clock tower in Hornsey, North London), which serves as a local symbol for the lodge.
