LancasterHistory will hold a History Happy Hour event on Monday, March 10, at Decades, 438 N. Queen St., Lancaster. Doors will open at 5:30 p.m., and the main program will begin at 6 p.m.

Attendees will learn about the history of the building now occupied by a vintage arcade, bowling alley, and restaurant. Three speakers will discuss the building's role in Lancaster's military, sports, and media history.

The building opened in 1916 and was named the Stahr Armory in 1956 after Lancaster's Dr. Charles P. Stahr, a brigadier general in the Medical Corps of the Pennsylvania National Guard. Over a 100-year period, the armory served as home to the Pennsylvania National Guard and the Lancaster Red Roses of the Continental Basketball Association and as a community space for food bazaars and performances. It was eventually transformed into Decades.

Tickets include admission to the event, one drink, light appetizers, and complimentary tokens for arcade games. Additional drinks may be purchased separately. The event is suggested for people age 18 or older, and individuals must be 21 years or older to consume alcoholic beverages.
