Several major department stores, two large hotels and an ice rink (beneath an arched glass ceiling) anchor Houston's largest shopping complex. Designed after a plaza in Milan, Italy, the center dominates the Uptown Houston district, west of Loop 610 and north of US-59 (Southwest Freeway). Immediately south of The Galleria, the 64-story Williams Tower offers a vast view from its top floors. The energy-company headquarters is one of architect Philip Johnson's best-known neo-Deco designs, a soaring, glistening, cathedral-like spire. The adjoining Water Walla kinetic sculpture, designed by Johnson and John Burgee, is a popular family attraction-especially on hot days, when it launches a cooling spray.
