It was erected in 1921 and enlarged in 1929-31 with a 14-story front addition.","why_significant":"The nomination presents the Exchange as the second largest securities exchange in the United States and the best surviving symbol of outdoor curbstone securities trading in New York. The organization began as the street-based Curb Market and moved indoors in 1921. It served as a proving ground for new corporations and developed the American Depository Receipt system for trading foreign securities.","narrative":"Home to the American Stock Exchange since 1921, this Lower Manhattan building at 86 Trinity Place is the only headquarters the institution has ever occupied. The original gray brick structure, designed by Starrett and Van Vleck and built by Thompson-Starrett, was enlarged between 1929 and 1931 with a 14-story steel-frame tower and an Art Deco limestone front. Behind it, the Italian Renaissance trading floor keeps its round-arched rear windows, marble wainscoting, dentiled cornice and coffered ceiling. The Exchange grew from the curbstone brokers who traded in New York's streets from the 1700s onward, expanding sharply after the 1849 gold rush. They organized formally in the early 1900s and moved indoors in 1921. The market became a testing ground for young corporations, several of which later joined the New York Stock Exchange. It also developed the American Depository Receipt system, now used for trading foreign securities in the United States.","period_of_significance":"Subject: 1849-present; Site: 1921-present","architect_builder":"Starrett & Van Vleck (architects); Thompson-Starrett (builder)","architectural_style":"Art Deco or Modernistic limestone facade; Italian Renaissance trading floor","criteria":[],"status_note":"Condition listed as excellent and the building is occupied; the upper floors are fully used by Exchange personnel and the trading floor remains in operation.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.752267-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/78001867_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78001867/84f0a63ad4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78001867/84f0a63ad4-1600.webp","licence":"CC BY-SA 4.0","author":"Sebaso","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Old_American_Stock_Exchange_Building_2009.JPG\" rel=\"noopener\">Sebaso</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Old_American_Stock_Exchange_Building_2009.JPG"},"district":{"nrhp_refnum":"07000063","name":"Wall Street Historic District","url":"https://nationalhistoricalregister.com/districts/new-york/wall-street-historic-district-07000063/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315910","wikipedia":"https://en.wikipedia.org/wiki/American_Stock_Exchange_Building","wikidata":"https://www.wikidata.org/wiki/Q16961338"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/manhattan/american-stock-exchange-78001867/"}
