"A gigantic relocation of material"[1]
Description
In order to maintain hydrstatic stability, ships need additional weight in their bottom part to make them stable. The weight is called ballast, and historically it consisted of sand, gravel or stones, but it could also be cargo or anything heavy. Brickstones were often used both as cargo and ballast, thus as 'paying ballast'. At the destination, the ballast was often discarded to make room for other cargo. Specific sites were shown for ballast dumping in order to prevent the harbour area from silting up. Over time, entire islands and additional land have been formed out of ship's ballasts. These sites are often unique from their surroundings, for example, flowers and plants not indigenous to their surroundings can grow on ballast dumping sites.
Ballast stones have been used to build roads and even whole city districts, such as the Bristol Basin in East Manhattan, USA.
