I photographed the Forest Park Visitors’ Center way back in September of 2012, on what was a cloudy day. I went back on a sunny day and captured these pictures.
There were more beautiful flowers out front here, as well. This is an interesting building, which started as a streetcar shelter, suffered a fire, and was rebuilt in the Spanish Revival style.
Interestingly, the tower, based off a Venetian campanile, is the oldest part. I suspect the upper portion of the tower is newer.
Here is an image of the pavilion before its partial destruction by fire.
