The estate was the personal residence of Andreas Syggros, a prominent 19th-century Greek financier and philanthropist.
It is one of the last remaining examples of the natural pine forests that once covered the Kifissia basin.
The interior of the estate includes experimental vineyards and olive groves used by the Agricultural University of Athens.
The Agios Andreas church on the grounds is a rare architectural example in Greece because it was built specifically to house the private collection of religious icons owned by the Syggros family.
The forest functions as an outdoor botanical classroom for students of agriculture and forestry.
Syggrou Forest is a 95-hectare protected woodland estate situated on the border of Marousi and Kifissia. It serves as a rare urban oasis characterized by its extensive pine forest and Mediterranean flora. The estate was bequeathed to the Agricultural University of Athens by Iphigenia Syggrou in 1921 for educational and experimental purposes. It remains a managed site featuring a network of dirt trails suitable for hiking, trail running, and mountain biking. The grounds house a distinct 19th-century Neo-Gothic mansion designed by Ernst Ziller. Visitors also find an 18th-century Orthodox church, Agios Andreas, built in a unique Byzantine style. The area functions as a research facility, prioritizing environmental conservation alongside recreational use.
