Mustangs at Las Colinas, Bronze sculpture in Las Colinas, Irving, US.

Mustangs at Las Colinas is a bronze sculpture by Robert Glen of nine wild mustangs at one and a half times life size, running through a shallow watercourse. Fountains in the water give the effect of splashing hooves. The horses cross a granite-paved plaza about 300 feet square, with the watercourse running 400 feet from northeast to southwest.

Robert Glen, a Kenyan sculptor born in 1940, was commissioned in 1976 and made the reduced models in his Nairobi studio. The bronzes were cast at the Morris Singer foundry in England, finished in November 1981, and the group was installed in 1984. SWA Group designed the sloping granite plaza and watercourse, a scheme that won a National Honor Award from the American Society of Landscape Architects.

The nine bronze horses commemorate the wild mustangs that once lived across much of Texas. Robert Glen, born in 1940, modelled the herd to convey the drive, initiative and unfettered lifestyle of the state's pioneer days. A museum beside the sculpture, in the east building of The Towers at Williams Square, shows a film about the work's creation and other sculptures by Glen.

The sculpture sits in Williams Square, open on its south side to O'Connor Boulevard; the surrounding towers rise 26 floors to the north and 14 floors to the east and west. The DART Orange Line stops at Las Colinas Urban Center and Irving Convention Center stations. The Mustangs of Las Colinas Museum is in the east building of The Towers at Williams Square, next to the sculpture.

Robert Glen modelled the horses as reduced maquettes in his Nairobi studio before the bronzes were cast at the Morris Singer foundry in England, a process finished in November 1981. The nine figures are set at one and a half times life size, and the group is counted among the largest equestrian sculptural groups in the world.
