The Burj Al Arab & the Wave

built like a sailboat out in the Persian Gulf.

Wikipedia: “Several features of the hotel required complex engineering feats to achieve. The hotel rests on an artificial island constructed 280 m (920 ft) offshore. To secure a foundation, the builders drove 230 forty-meter-long (130 ft) concrete piles into the sand. Engineers created a ground/surface layer of large rocks, which is circled with a concrete honeycomb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea, while it took fewer than three years to construct the building itself. Inside the building, the atrium is 180 m (590 ft) tall. Burj Al Arab is the world’s third tallest hotel.”
