Boscov's opened before the mall on September 19, 1992, and was the chains first store constructed in Central/Western Pennsylvania.[10] The Johnstown Galleria was built by Zamias Services, Inc. and opened on October 22, 1992, with space for a fifth anchor that was never filled.[2][3][11] It opened with anchors Bon-Ton, Boscov's, J. C. Penney, and Sears.[11] The Boscov's, former Bon-Ton, and former Sears buildings are independently owned.[2][12][5] Zamias sold the mall to Gemini Real Estate Advisors for $57 million in 2008, but remained as management.[2][13]
Steve & Barry's had a small format store open for a short time at the mall in the late 2000s.[14][15] Adar Johnstown Limited Liability Corporation purchased the property the mall is located on in 2014.[16] Pax Mall Realty settled a tax dispute with Cambria County over the value of the Boscov's anchor in 2017.[17] Bon-Ton closed at the mall in late April 2018 and was the first anchor to close in the Galleria.[18][19] Sears closed in summer 2018.[20][21] The mall's owners in 2018 won a tax reassessment from the Richland School District in court, reducing the mall's value from $6.5 to $3 million.[22] Parking lot and road conditions were reported as poor in March 2019.[23]
Spinoso Real Estate Group took over management from Zamias Services, Inc. on February 1, 2020, due to the mall entering receivership.[12] ADAR Johnstown Limited Liability Co., the owner of the mall's property, owed $14.6 million and stopped mortgage payments in October 2019.[12][9] The Galleria was scheduled to be sold at a tax sale on September 14, 2020, due to owing $1.1 million in taxes.[24] It was later removed from the sale due to the mall's owner, Adar Johnstown, LLC, setting up a payment plan. The Galleria was to go for sheriff's sale on December 11, 2020, but that was later delayed.[25][26]
The mall served as a COVID-19 vaccination site in early 2021.[27] The Johnstown Galleria was sold at sheriff's sale to the U.S. Bank National Association for $238,718 on September 10, 2021.[28] The mall minus the separately owned anchor buildings went to auction in August 2022 and sold for $3,150,000 to Leo Karruli.[4][29][30][31]
