The world’s highest sandcastle is now standing 16.68 meters tall in the German city of Duisburg. A German travel operator organized the construction of the mammoth sandcastle, bringing in 3,500 tons of sand over the past three and a half weeks to the site at a former steelworks in the inland city. It takes the title from a 14.84-metre sandcastle built early this year in India by sand artist Sudarsan Pattnaik.
