Built between 1795 and 1797, this historic structure is a three-and-one-half-story, brick building with stone accents that was designed in the Federal style. It was built as a "public office house" and housed the Commonwealth offices when Lancaster was the capital from 1799 to 1812.
This building, which was restored in 1924, has also housed city and county offices, a Masonic lodge, a post office, and library.[2] It now houses the Lancaster visitor's center.
