Edward James was a British poet known for his presence in the surrealist art movement. Las Pozas ("the Pools"), near the village of Xilitla, San Luis Potosí, more than 2,000 feet (610 m) above sea level in a subtropical rainforest in the mountains of Mexico, is a garden created by James. It includes more than 80 acres (32 ha) of natural waterfalls and pools interlaced with towering Surrealist sculptures in concrete. Massive sculptures up to four stories tall punctuate the site. The many trails throughout the garden site are composed of steps, ramps, bridges and narrow, winding walkways that traverse the valley walls. Construction of Las Pozas cost more than $5 million dollars. To pay for it, James sold his collection of Surrealist art at auction.
