Pacmen64 🇵🇹
April 11, 2025, Lapa de Santa Margarida

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.

During the tour, you will have the opportunity to discover the origins of Azeitão, a town located in the heart of the Arrábida Natural Park. The name Azeitão, of Arabic origin (azzeittum), refers to the vast olive groves that once covered the region. Its origins date back to the Middle Ages and, over the centuries, agriculture, especially viticulture and olive cultivation, shaped the landscape that still characterises the region today, with farms and small settlements that maintain these traditions. Azeitão gained renown from the 15th century onwards, when it became one of the favourite places of the Portuguese nobility, being shaded by the majestic Serra da Arrábida. The route begins and ends in Vila Nogueira de Azeitão and passes through several historic villages, including Aldeia Rica, Oleiros, Aldeia de Irmãos, Piedade, Portela, São Pedro, Casais da Serra and Picheleiros, always under the imposing presence of the Serra and its traditional paths.

Hello everyone.

The climb was intense but the path was passable. On the other hand, the descent was not at all enjoyable, there were prickly holly-like plants for a good hour, bring suitable pants otherwise your legs take a hit and the walk goes badly.
