Pasadena is Houston's most populous suburb and the former location of "Gilley's", the honky-tonk bar that inspired the hit 1980 movie Urban Cowboy, which was filmed in Pasadena. Because of its location skirting the ship channel where most of the city's refineries are located, Pasadena is considered the backbone of Houston's enormous petrochemical complex. The nearby cities of Baytown, La Porte, which is home to the San Jacinto Monument, and Channelview are also host to many refineries and chemical plants. Other nearby cities are Deer Park, Galena Park, and South Houston.
