This large public park located in the center of the city was opened in the 1920s. It encompasses an open-air cinema, ancient ruins, a botanical museum and a café where you can sit and enjoy the peace and quiet.
If you're heading out with your children, there is a small ZOO, a duck pond and playgrounds that will keep them busy.
Admission to the garden is free.
