Holding the Olympic Games in a country is an unparalleled event. However, some venues were built specifically for the Olympic Games but were later abandoned after being unable to be fully utilized. It is also a pity that such examples are not in the minority. It should be well planned like the Bird's Nest, and host sports competitions or concerts to continue it.

Moscow hosted the Summer Olympics in 1980, but after the Soviet Union invaded Afghanistan, they launched a massive boycott of the Games. About 60 countries refused to participate in the Olympics, but this did not stop the Soviet Union from building some new venues in 1984. The Estonian city of Tallinn hosts the sailing competition and they are redesigning their Olympic venues. The Olympic Sailing Center is still in use and has become a hotel, spa and casino, but the surrounding Lenin Palace is not so lucky. According to Estonia, in the years following the Olympics, the sprawling concrete building known as "Linach" was used as a concert hall and it even had a then-state-of-the-art recording studio. By the 1990s, it wasn't quite as cutting-edge. After years of neglect, it was finally abandoned in 2009.

Although Greece has achieved relatively good results after its first Olympics, the country's finances are not so easy, and abandoned venues like the Olympic Aquatic Center have to add insult to injury. In the run-up to the 2004 Olympics, the Athens government invested $12.2 billion to build venues that could be seen by everyone in the world. By 2008, their debt had reached $460 billion, and while that makes $12 billion seem like a relatively small number, there's still plenty of money that could be spent elsewhere. Ten years later, the complex was completely abandoned and baking in the Mediterranean sun.
