Loch Ness is part of the Great Glen or Glen Mor in Gaelic, a
scar-like fault line that runs over 60 miles from Inverness in
the north to Fort William in the south. It is made up of three
lochs - Loch Lochy, Loch Oich and Loch Ness - with Loch Ness being
by far the largest with a surface area of 56.4 square km (21.8
square miles).
Although Nessie was sighted as far back as the 6th century AD it
is the modern day sightings that have captured the public
imagination. In the early part of the 1930s a new road was built
around Loch Ness that in turn brought in a spate of new sightings
from drivers and sightseers.
