Carrasqueira is probably the most traditional of the small villages in Comporta. It is located 1:15 from Lisbon, on the banks of the mouth of the Sado River, opposite Setùbal. It is famous for its port on stilts, with old wooden mooring lines for the local fishing boats. Carrasqueira in Comporta also houses original fishing huts. Carrasqueira’s farmlands and estuary have been exploited by migrant workers who have settled in the traditional fishermen’s huts over the years. They have been preserved and used in this way for decades. They are also known as “Comporta cabanas” and are the inspiration for more recent constructions in the region that combine wood, traditional masonry and thatched roofs. These fishing huts are now protected and are part of Comporta’s historical heritage. The village of Carrasqueira has a large main street where most commercial activities are located. This includes restaurants, bars, cafes and some small general stores and supermarkets.

The chapel was probably built in the 17th or perhaps 18th century, as a place of Christian worship that, most likely, succeeded other previous cults, namely those related to water or even initiation rites linked to the idea of the rebirth of the soul.

Lapa de Santa Margarida is a natural grout at the base of Arrábida Mountain, where a small altar was erected. The access is done by a narrow path, with over 200 steps, until the sea level. Inside there is a Christian altar with some images and candles. The image of Saint Margaret was initially in this chapel, thus having given her name to this place.

This linear route runs along the northern and southern slopes of the Serra da Arrábida up to Portinho da Arrábida, passing through the highest point of the mountain range, Alto do Formosinho, marked with a geodesic marker at 501 metres. This route, which is of the highest level of difficulty, is the closest to mountaineering conditions, due to the steep incline and the characteristics of the terrain. It is one of the most charismatic routes in the region, due to its connection to the first settlements of Arrábida (Castelo dos Mouros rock formation) and the ancient pilgrimage candles of devotion to Our Lady of Arrábida, which are still maintained, due to the challenge of reaching the peak, through dense vegetation, areas of gravel and rock climbing, and also through the endless landscapes that connect the Sado estuary to the Tagus and the border between Finisterra and the ocean.
