This is a large green park, with nice gardens and much shade provided by trees. There are flower beds, a small lake, Roman mosaics, and ancient ruins. All these are near artistic sculptures, botanical gardens, and a small animal zoo that is located near the garden.
The National Gardens were planted in 1840, by the Queen Amalia of Oldenburg. She ensured the garden's construction around the royal palace of those days, and they became her royal gardens. Today they are open to the general public, and located near that same palace, that has since been turned into the Greek Parliament building.
With lots of playgrounds, wandering peacocks in the gardens and nice fountains, a visit here is recommended for families with children and travelers. In the nice and shaded gardens are attractions for children, small lakes, fountains and pools, with ducks swimming around, and even a small zoo.
It's possible that lively young people looking for excitement might not find it here in the park, but will be able to rest for a short while, while on their way to see all the extraordinary sites in Athens.
