[3] Among the municipality's features one notices the low rise profile with four apartment floors maximum at the center, while particularly high is also the rate of private gardens.

In antiquity the area of Vrilissia formed part of the deme of Phlya, which covered the land spanning from Psychiko to Agia Paraskevi and mainly centered on what is now known as the Municipality of Chalandri.

After long-lasting conflicts, the Naval Base region was transferred to the municipality with an official ceremony, while many small parks were created in each neighbourhood.

The word "Vrilissia" is a plural form of a neuter noun (τα Βριλήσσια) referring to the land of the Great Rock Mountain (Penteli).

Vrilissia is an affluent suburb with several schools spanning all grades, sporting grounds and parks; it is also home to a large commercial district with a number of banks and several malls within its territory.

Vrilissia has exceptionally wide, straight roads, in stark contrast to those typically found in Athens, and is also relatively green, with most houses/apartment blocks extending to gardens.

At that time, Penteli constituted a popular destination for day excursions for Athenians, as well as picnics, walks in the forest, a stop for a coffee, or dinner at the local taverns.

When urban housing projects began reaching Halandri, Vrilissia and Melissia, Penteli started to transform into a residential landscape.

Around this time and in stark contrast to the lower-density provisions afforded for the Ano Vrilissia settlement below the Anapafseos Avenue, the hill was allowed multi-floor apartment blocks (up to five levels), in the process compromising the aesthetics of the Penteliko scenery.

The south area of the hill looking at the Athens basin was included in the urban design of Vrilissia and the street layout approved was implemented.

The latest proposals of the municipal council suggested concession of 500 m2 (5,400 sq ft) per household to those who abide by the criteria of the law (that allocate titles of purchase of the land inhabited).

Finally, a pine-clad area of 0.088 km2 (0.034 sq mi) was preserved around the northern borders of the municipality, up to the neighbouring suburbs and reaching the Halandri gullies to the south, a natural protection of the city from the traffic and exhaust.

Even today, with the important new transportation projects built, and the trading development, Vrilissia's climate is still considered to be clean, offering ideal conditions of living to its residents.

The thought prevailed in the court was that the wide region of "Gerotsakouli" (Γεροτσακούλι) had been owned by the abbey since its foundation in 1578 by Saint Timotheos Mentelis, Bishop of Evripos partially by donations from devout Christians and by purchase in 1600 by the Ottoman from Karystos of Evia named Kagadis with muniments that were destroyed during the Greek liberation by the army of Omer Vryonis.

However, it only until the July 2007 that the Appellate reached a verdict on the same case which vindicated the individual claims on the same argument and which did not even accept the procedural intervention of the Municipality at the Court.

Even the great Naval Base, a junction of interests, is struck, although the greater part of its reformation project to turn it into a park is completed.

Adjacent Municipalities with forest heritage begin volunteer projects of surveillance by residents (such as Pefki and Vrilissia) while the Chalandri gully is also struck, only a few metres away from the local fire brigade department.
