, Cameron County
Built in 1848 for J.E. Garey and Company, this structure under subsequent ownership has housed a "drinking house", boutique and was the residence of Brownsville's first mayor, Robert S. Leman. The Gem is an excellent local example of mid-19th century commercial architecture influenced by vernacular traditions. Features include a five-bay facade, second floor balcony with full-length shutters, first floor french doors, and detailed corbelled brickwork.
