Chartered on June 24, 1765, by the Grand Lodge of Pennsylvania A.Y.M., Lodge No. 5 at Cantwell's Bridge, later known as Odessa, became the first Masonic lodge established in Delaware. The lodge was admitted to membership under the Grand Lodge of Delaware in January 1816. Lodge No. 5 moved to Middletown in 1822 and adopted the name Union in 1851. With uninterrupted service to the community, Union Lodge No. 5, Ancient Free and Accepted Masons, is distinguished as one of the oldest continuous organizations in the state of Delaware.
