About Katy

Learn more about the host city, Katy.

Katy is a town in Southeastern Texas, just west of Houston, with rich history and a little bit of small town charm. It used to be a railroad town along the Missouri–Kansas–Texas railroad. In the 1960s, Houston started growing, eventually making Katy part of its surrounding area. Katy is a place to see for its heritage and historical sights, as well as other attractions to visit, with many being more popular than historical locations.
