Classes began within months after the charter was granted, offering a college preparatory track (including intensive study of Ancient Greek, and Latin) and an arithmetic-based track to prepare young men for Albany's role as a center of commerce. Two years later, in 1815, a purpose-built building was completed in present-day Academy Park, adjacent to the New York State Capitol. The Federal-style building, now known as the Old Academy and headquarters of the City School District of Albany, was designed by renowned Albany architect Philip Hooker. The building is listed on the National Register of Historic Places for its architectural significance and role as home to scientist Joseph Henry's laboratory.
