The National Garden is a park area of ​​15.5 hectares in the center of Athens. When we also include the Garden of Zappeion with an area of ​​13 hectares then the total area of ​​the two parks together is 28.5 hectares (285 acres). The initial name, up until 1974, was the "Royal Garden". The park is next to the Greek Parliament and extends to the south where Zappeion Megaron is located, opposite the Panathenaic stadium where the first Modern Olympic Games took place in 1896. There are still ancient ruins, columns, mosaics etc. in the garden.

The small historical island of Hydra is the most cosmopolitan island of the Saronic Gulf. Hydra is a long narrow island (​​52 square kilometers in total) and it is just 6 miles from the Peloponnese. The island got its name from the water that sprang from there in antiquity. It is an island with a rich maritime tradition and played an important role in the revolution of 1821, along with the island of Spetses and Psara. If you take a walk around the island, you will see the old mansions, museums, cannons and turrets of the harbor.

This is the most famous monument of the island. It is also called "Fortezza" and was built in the 13th century when the island was dominated by the Venetians. The castle was also known as the “eye of Crete" due to its strategic position. Someone watching the sea from the castle could notice boats or enemy ships in three places simultaneously: the Ionian Sea, the Aegean Sea and the Cretan Sea. The castle was built in different phases of the history of the island, but the biggest and most important part of the facade was built in 1503 by the Venetians.

Parnitha (west side of Athens) is a diverse group of peaks with very rich fauna and flora. Karavola is the highest peak (1,413 meters) while sixteen more peaks are above 1000 meters high. The forest is mainly comprised of firs and pines but there are also many other trees and plants which provide food and shelter for the animals that live on the mountain. Approximately 1100 plant species are recorded and 90 of these are Greek endemics. The establishment of the Parnitha National Park in 1961 helped the conservation of the biodiversity of the mountain.
