Location

Located in the serene locality of Casais de Santo Quintino, in the municipality of Sobral de Monte Agraço, district of Lisbon, lies the Forte do Trinta, also known as Forte da Direita.

Its remains are strategically implanted in the landscape, taking advantage of the region's natural topography. This location, once fundamental for military defense, today offers a tranquil and rural environment, inviting contemplation of the surrounding countryside.

The Legacy of a Historic Defense

This site, designated as Work nº 16, represents a significant fragment of an ingenious large-scale defensive system, erected in the early 19th century.

Its existence testifies to a critical period in Portugal's history, when the nation was preparing to repel invaders, decisively protecting the capital. Although they appear today as remains, these silent ruins echo the steps and determination of those who once garrisoned these positions.

Remains and Military Architecture

As a visitor, you will find here the remains of what was a robust structure of military architecture. Its foundations and some remaining elements allow a glimpse into the functional simplicity and solidity of these constructions.

A fort, in this context, was a field fortification, designed for rapid construction and maximum defensive effectiveness. It is an invitation to imagination, to mentally reconstruct the fort in its fullness, understanding its strategic importance in the terrain in which it was inserted.

Scenic and Contemplative Value

Despite being a site of military memory, Forte do Trinta also offers intrinsic scenic value. Its implantation on elevated ground provides clear views over the surrounding rural landscape of Sobral de Monte Agraço.

It is an ideal space for a peaceful break, allowing the visitor to absorb the serenity of the countryside while reflecting on the past that unfolded there, and the role of these constructions in the defense of a territory.
