[4] The second phase of renovations gave the mall a Southwestern theme, adding skylights and an octagon-shaped stage, as well as marble floors and new fountains.

[6] The incidents eventually resulted in Simon terminating the leases of the VIA transit facilities at Windsor Park and its other San Antonio malls.

[7] In 1994, an altercation inside the mall disrupted holiday shoppers when two teenagers got into an argument that escalated into gunshots; the victim died of his injuries.

[10] The crime and resulting safety concerns began to take their toll on the success of Windsor Park, and by 2001, Simon considered using the mall as a small business incubator.

The company was rapidly outgrowing its newly leased corporate headquarters, which were in a building formerly used by Datapoint on the northwest side of San Antonio; seeking even more space, Rackspace bought the mall for $27 million.

[23] Renovations also added environmentally friendly features such as a rainwater cistern and dual flush toilets; in 2009, The Castle received LEED Gold certification.

[22] Among the features of The Castle are a two-story slide, 80 conference rooms, cable car-type gondolas repurposed from the closed Sky Ride at Brackenridge Park,[25] a coffee shop and fitness center[24] and art installations.
