Harrisburg Technical High School
Also known as: Old City Hall
Why it's listed
Built in 1910 on Walnut Street across from the State Capitol in Harrisburg, the front block of Technical High School was designed by architect Charles Howard Lloyd in the English Collegiate style, with brownstone trim, triplet windows, and a carved owl above the main entrance. It was attached to a 1905 brick shop addition built to carry heavy vocational machinery. The school was one of the city's early public vocational programs, with enrollment reaching 644 boys by 1920. The school closed in 1926, and in 1929 the building was converted by Lloyd into Old City Hall, housing municipal offices in one place for the first time. Its lobby, grand staircase, and former Mayor's office remain notable interiors. The building served as the seat of city government for 53 years, and its design reflects both the educational and civic roles it played in the capital city's development.
Significance in brief: The nomination argues the building is significant in education as an early 20th century public vocational training school, in architecture as a well-designed work by architect Charles Howard Lloyd in the English Collegiate style, and in politics and government as the seat of municipal government from 1929 onward. The 1905 shop addition is also noted as a facility built to handle heavy machinery.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
