Mustangs at Las Colinas is a bronze sculpture by Robert Glen, that decorates Williams Square in Las Colinas in Irving, Texas. It is said to be the largest equestrian sculpture in the world.
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.
