Today, I would like to present to you: The Central Park
The CentralPark is a very famous public park at the Center of Mannhatten in New York City.
The Park opened in 1857, with 315Ha.
Frederick Law Olmsted and Calvert Vaux won a design competition to improve and expand the park. The Construction began the same year and was completed in 1873.
The Central Park is the most visited Park in the United States, the second largest park in the world and only the English Garden in Munich is larger.
There are 36 bridges and 21 playgrounds in Central Park
For visitors they´re interested in history the center park has a lot to offer. Again and again monuments were consecreted here. The first monument was for Friedrich Schiller.
The Central Park has a big lake, where you can be rowed on and also a zoo.
But there is even a several “secret” garden worth a visit, smaller planting sites just created to attract butterflies and other insects.
