1. Helsinki Zoo, also known as Korkeasaari, is situated on an island in Helsinki, Finland. It is the country’s oldest and largest zoo, founded in 1889. The zoo is home to over 150 animal species and around 1000 plant species.

- One interesting fact about Helsinki Zoo is that it was the first zoo in the world to successfully breed the endangered Saimaa ringed seal, which is endemic to Finland’s Lake Saimaa.

- The zoo’s facilities include various themed areas such as the Amazonia, Africasia, and Borealia, which represent different animal habitats from around the world. Visitors can explore these areas and witness a wide range of animals, including lions, tigers, polar bears, monkeys, and more.
