Historic Colleyville

At first glance, one would assume that a city like Colleyville, which was only incorporated in 1956, would not have much history.  But in reality, the first settlements in the area date from as early as the 1850s:  Red Rock, Bransford, Glen Hope, Pleasant Glade, Pleasant Run, and Spring Garden are all communities that are now part of the city of Colleyville.
