The video discusses the connection of the Great Lakes and Scottish lochs via canals, focusing on the Caledonian Canal built over 100 years ago. This canal, with its series of locks known as Neptune's staircase, allows ships to travel across Scotland without navigating the northern seas, saving 400 miles. The construction was led by Thomas Telford, a prominent engineer of the early 19th century, whose work has facilitated countless peaceful maritime journeys.
