Loch Ness is known as the home of the Loch Ness Monster (also known as "Nessie"), a cryptid, reputedly a large unknown animal. It is similar to other supposed lake monsters in Scotland and elsewhere, though its description varies from one account to the next. Popular interest and belief in the animal's existence h varied since it was first brought to the world's attention in 1933. Loch Ness is the second largest Scottish lochby surface area at 56 km2 (22 sq mi) after Loch Lomond, but due to its great depth, it is the largest by volume in the British Isles. Its deepest point is 230 m (126 fathoms; 755 ft), making it the second deepest loch in Scotland after Loch Morar.
