[1] In 2001 its resident population was approximately 17,830 inhabitants, covering an area of 3.6 km2,[2] west of Lisbon on the coast near the mouth of the Tagus estuary.

[3] Professor Diogo Correia, in his book Toponímia do Concelho de Cascais, refers to the topology in these terms: "In the opinion of authoritative specialists, the walls that gave the name to the homonymic settlements, were from ruined castles, dismantled redoubts, and many times, hilltop rocks.

[3] Branca Colaço and Maria Archer, later confirm these ideas in their explanation for the locality: "...Parede...its old name, of three or four centuries...topology that many suggest from the many walls of loose rock, that were used to circle their properties...which even today are maintained, and that others attribute to the local terrain's structure, rich limestone in quarries, which, for centuries, were used in the construction of the walls of Lisbon".

At that time, it received administrative autonomy, bringing with it the places of Buzano, Junqueiro, Madorna, Murtal, Penedo and Rebelva.

It is one of six civil parishes that comprise the municipality of Cascais, bordered on the south by the Atlantic Ocean, east by Carcavelos, north by São Domingos de Rana and in the west by Estoril.
