The tallest sandcastle is 13.97 m (45 ft 10.25 in) tall and was created by Ted Siebert (USA) of the Sand Sculpture Company and a crew of 19 on behalf of Turkish Airlines, in Virginia Key Beach, Miami, Florida, USA, on 27 October 2015. Using 1,800 tonnes of imported sand, the team worked for two weeks to create the tallest sandcastle.
Turkish Airlines wanted to celeberate their special occasion of bridging Miami to more than 270 destinations via Istanbul in a fun and unusual way. They gifted Miami residents by bringing together 19 sculptures from all around the world by building the largest sandcastle - EVER! - 4500 Square foot, 45 feet 10.25 inches tall.
