Mustangs at Las Colinas
The sculpture commemorates the wild mustangs that were historically important inhabitants of much of Texas. It portrays a group at 1.5 times life size, running through a watercourse, with fountains giving the effect of water splashed by the animals' hooves. The horses are intended to represent the drive, initiative and unfettered lifestyle that were fundamental to the state in its pioneer days.
The work was commissioned in 1976 and installed in 1984. SWA Group's design created a shallow watercourse extending 400 feet (130 m) from northeast to southwest across Williams Square, a gently sloping granite-paved open space about 300 feet (110 m) square. The plaza setting for the sculpture won a National Honor Award from the American Society of Landscape Architects.
The buildings around the square rise 358 feet (26 floors) on the north and 217 feet (14 floors) on the east and west sides, with the south side open to O'Connor Boulevard. The sculpture is substantial, but the scale of the surrounding structures keeps it from dominating the space.
Beginning July 30, 2012, the DART Orange Line extends to the Las Colinas Convention Center and the 503 circulator bus begins operation and it will be possible to visit the site without a car, by walking or biking from a bus stop.
