Rockville developer eyes conversion of historic Reservoir Hill mansion to food hall

A vacant, historic mansion in Reservoir Hill could be redeveloped into a food hall under a new plan by Rockville developers. Marbray & Co. Realty LLC was recently selected as the frontrunner from a request for proposals to redevelop the 230-year-old, city-owned Birckhead Estate, also known as the Birckhead-Bond House or Mount Royal Mansion, at 2001 Park Ave. The three-story stone structure has an eclectic and interesting history, including once being owned by Orioles owner Peter G. Angelos.
