* The ancient Olympic Games were always held in Olympia, Greece.
* The modern Olympic Games were first held in Athens in 1896, and were held there again in 1906, as the first of a second series of Olympic Games, the intercalated games, to be held in Anthens every four years in between the games being organised by cities around the globe. Though Athens 1906 had a big influence on the Olympic movement, the series didn't continue, making 1906 a bit of an exception, usually ignored in lists about the Olympic Games.
* Paris was the first city to host the Olympic Games twice, hosting them in 1900 and again in 1924. (Ignoring the intercalated games.)
* Counting the intercalated games, Athens was the first city to host the modern games trice: 1896, 1906, 2004.

There was no Summer Olympics in 1966. 1964 was hosted by Tokyo, Japan and 1968 games were hosted by Mexico City, Mexico.
Barcelona, Spain hosted the Olympics in 1992.
Taiwan, or Chinese Taipei as it is recognised by the International Olympic Committee, has never hosted the Olympics. In fact technically a country never hosts the Olympics; they are awarded to a city. So, for instance, London, of which the British are justifiably proud, has hosted the games three times, but the USA has hosted the games more times, as they have been awarded to various cities (St Louis, Los Angeles twice, Atlanta, Lake Placid twice, Squaw Valley and Salt Lake City). If the games were ever to be held in Taiwan, they would probably be awarded to Taipei, which is Taiwan's biggest city.
