The Mercer Museum is a six-story reinforced concrete castle designed by Henry Mercer (1856-1930) and completed in 1916. Today, it is one of Bucks County’s premier cultural attractions and a Smithsonian affiliate.

The museum complex features local and national traveling exhibits, as well as a core museum collection of over 17,000 pre-Industrial tools. This permanent collection offers visitors a unique window into pre-Industrial America through sixty different crafts and trades, and is one of the world’s most comprehensive portraits of pre-Industrial American material culture. The museum also features a research library that is a center for local history related to Bucks County and the surrounding region, with its roots dating back to the founding of the Bucks County Historical Society in 1880.
