Windsor Park Mall was a shopping mall located on the northeast side of San Antonio, Texas, off Interstate 35 and Walzem Road. It was opened by Melvin Simon and Associates in 1976 as San Antonio's first four-anchor shopping center, adding a fifth anchor space in 1985. After Simon opened Rolling Oaks Mall in 1988 and the mall experienced a series of crime incidents in the 1990s, it declined. All of its anchors closed between 2001 and 2005, with the mall itself closing along with Mervyn's in 2005.
In 2007, the building, of which ownership was transferred to the suburb of Windcrest, Texas, became the new corporate headquarters of Rackspace, a Web hosting company. Their redevelopment of the mall structure, now known as "The Castle", sparked a redevelopment of the surrounding area. Rackspace remained in the area through 2022, when it announced its intention to vacate the property, which was underutilized due to increased remote work. In early 2024, the building was sold to Industrial Commercial Properties LLC, becoming known as the Windcrest International Business Park.
