The front portion was built in 1910 and later served as Harrisburg's Old City Hall.","why_significant":"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.","narrative":"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.","period_of_significance":"1905-1910","architect_builder":"Charles Howard Lloyd (architect)","architectural_style":"English Collegiate (collegiate Gothic)","criteria":["A","C"],"status_note":"Adapted for municipal use as Old City Hall in 1929 and served as the seat of city government for 53 years","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.748611-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/82001533.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82001533/52cf70688b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82001533/52cf70688b-1600.webp","licence":"Public domain","author":"Pubdog (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Harrisburg_Technical_High_School_Nov_10.JPG\" rel=\"noopener\">Pubdog (talk)</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Harrisburg_Technical_High_School_Nov_10.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995809","wikipedia":"https://en.wikipedia.org/wiki/Harrisburg_Technical_High_School","wikidata":"https://www.wikidata.org/wiki/Q15223091"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/dauphin-county/harrisburg-technical-high-school-82001533/"}
