This amusement park in North Rhine-Westphalia, Germany is built at an abandoned nuclear reactor site. The power plant was never put to actual use due to the protests and limited resources. Dutch entrepreneur Hennie Van Der Most bought the site and turned it into an amusement park. Wunderland Kalkar receives more than 600,000 visitors every year.Check out this video.
2.Olympia Park: The history brings a lot of things for this awesome venue with the unfortunate event in the past, but now this place has moved on to offer a magical view along with the lake and greenery. you will see a lot of people enjoy with their families on any other day :)It was getting cold as the sun was almost set but still I didn't feel like going back to the hotel. The green pathways were full of people jogging in the park. Along the lakeside, few kids were playing and feeding the Ducks. This park was spread for miles and miles so I decided to skip the rest of the park :D
