Bayernhof Music Museum features a major collection of automated musical instruments from the 19th and 20th centuries. Located six miles (10 km) northeast of downtown Pittsburgh in the suburb of O'Hara Township, Pennsylvania, it is housed in German-style mansion sited on an 18-acre (73,000 m2), dramatic overlook some 540 feet (160 m) above the Allegheny River Valley. The museum was a directive of Mr. Brown's will and it opened to the public in 2004.
