Parque de La Ciudad
Parque de La Ciudad was planned during Argentina's Military Government, around 1975. They wanted to build a large amusement park with all new rides, and money wasn't an issue. They contracted a company named Interama Parks S.A. to be in charge of everything, and this company contracted Intamin AG to built a giant observation tower, and to provide the park's major rides, including the only steel racing coaster in the world at that time.
They planned two major rollercoasters, Vertigorama, Intamin's steel racing coaster, that cost US$10.000.000 and Aconcagua, a Schwarzkopf model pretty much like Nessie, without the looping. Is was South America's highest coaster for a long time, and it cost was around US$6.500.000.
When the park opened it's doors in 1982 it had 62 attractions. Vertigorama wasn't one of those, since it's electrical parts never came to place.
The return to the democratic government, along with a long recession period were some of the factors that contributed to the closing of the park in 2003 when Buenos Aires' mayor decided to close the park claiming that he wanted to refurbish all the rides. The park remained closed for 4 years. In 2007 it reopened with just a few attractions, but it was closed again in 2008, when the city government claimed that the park's rides were not safe.
Nowadays the park is partially open. People are allowed in the center areas, where the picnic tables, lake, restrooms and green areas are. The observation tower, called Torre Espacial reopened last year, but I'm not sure wether it's still working or not, since it was closed on the day of my visit.
I was always amazed by abandoned parks, so this visit to Parque de La Ciudad was very, very special to me.
In 2013 there's going to be a huge music concert at Parque de La Ciudad, so I'm afraid they'll remove the rides for good. If you have the opportunity to visit this park while the rides are still there, please do, it's really amazing!
