Some landmarks are designed to stand out: DC’s Washington Monument, London’s Big Ben, Russia’s the Motherland Calls (a sword-wielding stone woman who reaches nearly 300 feet!). But other marvels are easy to miss if you aren’t looking for them.

In contrast to its towering warrior, Russia houses the smallest public monument in the world. The tiny frog statue, named the Frog Traveler, sits at only 1.7 inches high! It was inspired by the Russian children’s book The Frog Went Travelling, and pays homage to all travelers of the world.

You may have been to the Washington Monument, but did you know that it has a mini-me buried nearby? This 12-foot replica is officially called “Bench Mark A” and serves as a geodetic control point—a point of reference for creating accurate maps. If you want to see it for yourself, you’ll need a park ranger to help you open the manhole cover!

London has an even smaller sight to hunt for. High up on the side of a building on Philpot Lane is the Two Mice Eating Cheese. These mice may be cute, but they have a devious past. Supposedly they commemorate two construction workers who fell to their deaths in a fight after one accused the other of stealing his cheese sandwich. The real thieves got away squeaky clean.

Stockholm is home to the Järnpojke, the Iron Boy (also called the “little boy who looks at the moon”). This monument is less than 6 inches in height and has been sitting in Old Town for 50 years. In the winter, visitors even dress him in warm clothes!

I know on my next vacation, I’ll be sure to keep an eye out for small wonders like these!
