The world’s largest recorded iceberg, was Iceberg B-15, which measured around 183 miles (295 km) long and 23 miles (37 km) wide, with a surface area of 4,200 square miles (11,000 sq km) – making it larger than the whole island of Jamaica. In 2000, the Iceberg B-15 broke up into smaller icebergs and later drifted away into the sea.
