Completed in 1940, Torre do Castelo is an 88-foot conical shaped tower located in Campinas, Brazil. Originally it served as a 66,000-gallon water tank for the city, but today it is a historical museum and popular landmark in the region.
Styled with art deco architecture, it houses a museum and observation deck. Visitors can view historic pictures of what Campinas looked like at various time periods. Take the stairs to the top of the tower and see scenic views of the city.
The landmark is so high that it's possible to see the City of Serra Japi, which is almost 25 miles away. The tower is open to the public on weekends and admission is free.
