North Queensferry Lighthouse
If you’re wondering what the cutest building in the world it, we believe it to also be the smallest lighthouse in the world! Though this structure has since been decommissioned in 1964, it is still a grand little structure in North Queensferry, Scotland. Standing at a whopping 3.3 meters or 11 feet high, the lighthouse was built in 1817 by John Rennie, with a design by famed designer, Robert Stevenson. The trek from the bottom floor to the top of the light is a short, winding 24 steps. The housing for the light is so small that it can only fit two people, though comfort is definitely not guaranteed. The lighthouse was once used to guide the ferry passage that was done away with after the Forth Road Bridge opened, but now acts as a great tourist attraction, having been saved by the North Queensferry Heritage.
