Amsterdam, Netherlands: National Monument

History buffs know that the Netherlands did more than its share of suffering in World War II. Germany marched through it on the way to taking France, and held on to the little country for a few years.

Therefore, it's important to have a national monument in an important place to salute those who gave their lives in the struggle. The Dutch did that in 1956, creating the most important monument in the nation toward that purpose. It checks in at close to 70 feet.

The structure sits in Dam Square across the street from the Royal Palace. Every May 4, people gather with the Royal Family on National Remembrance Day to salute those who have made the ultimate sacrifice for the country.
