Summer Olympic History Fun Facts
• The very first modern Olympic games were the Summer Olympics held in 1896. Because Ancient Greece was the birthplace of the Olympic Games, Athens was considered to be an appropriate choice to stage the inaugural modern Games.
• London is the only city to host the Summer Games three times -- in 1908, 1948 and 2012. The Summer Olympics have been held in the USA four times (1904, 1932, 1984, 1996) - but in three different cities.
• The United States has won more gold and overall medals than any other country in the Summer Games. Summer Olympian Michael Phelps is the most-decorated Olympic athlete of any nation, with 22 Olympic medals (including 18 golds).
• Yes, it's true. Olympic gold medals aren't really made of solid gold, but silver with gold plating. Olympic gold medals haven't been pure gold for about a century.
• The modern games were only canceled three times, and it was always the Summer Olympics. The 1916 Summer Olympics in Berlin were canceled because of World War I. The 1940 Summer Olympics in Helsinki, as well as the 1944 Summer Olympics in London, were canceled because of World War II.
