As a kid you probably enjoyed making sandcastles on the beach but did you ever think sandcastles could be so big, so elaborate or intricate? Some take it seriously, very seriously. Amateurs, artists and businesses from around the globe compete to win the prestige, prizes and press attention from their sandcastles AKA sand sculptures, the more accurate term for this peculiar endeavour. Even the corporates at companies such as eBay take a good sandcastle seriously, eBay commissioned a monster 75 tonne sand sculpture for their 10th anniversary. These sand sculptures are typically made using river sand, which is a finer material when compared with beach sand and therefore more suited to being sculpted. Unlike your puny childhood attempt at sand castle glory, some of these oversized sandcastles withstand weeks of erosion before disappearing. Here are some of the finest examples of sand sculptures from around the world.
