Chesapeake and Ohio Canal<br> United States picture - This historic waterway runs through the heart of Georgetown. Each of these tiers you see were locks used to raise or lower boats so they could make the entire journey. Under the bridge in the middle ground, you can see the old lock gates folded back against the structure.
