Highland Hall (Hollidaysburg, Pennsylvania)
Highland Hall, also known as the Courthouse Annex, was a Presbyterian seminary, historic school building for females, radio school during World War II, and county office building before it became a retirement home that started in construction in 2016. Highland Hall is located at Hollidaysburg, Blair County, Pennsylvania. It was designed by noted Philadelphia architect Samuel Sloan and built about 1865. It is now a four-story, "L" shaped stone building. It features a mansard roof, a characteristic of the Second Empire style. It was originally built to serve as a Presbyterian seminary for both sexes. It became a female academy and officially named Highland Hall in 1911. It continued to be used as a girls' school until 1940. It became a county office building in 1969.
Highland Hall was added to the National Register of Historic sites Places in 1978.
Highland Hall has been turned into a 65 and older affordable housing facility constructed by Keller Engineers, and S&A Homes.
