This church is in mannerism and Pombaline style and it makes part of the Convent of São Domingos. Some of the elements were altered with the Pombaline reform, such as the façade, the lateral elevations and the decoration.

The façade of this building follows two different lines, one with several windows and doors around a central vertical body, and the other with several windows with iron grates. The back of the building was turned into a leisure and spiritual refuge area with three interesting architectural features: a small Swiss chalet (The Tea House), a revivalist and eclectic chapel and an interesting traingualar building, named the Hothouse.

Portal built with two door-posts and a lintel with five arches. The central arch has a shield. On the upper part is a Latin inscription.

Fountain built with white and pink marble, presenting a tank and water spouting from three masks in a salient body, on top of which are set three armillary spheres.

The current constructions date back to the 18th century. The church is sided by two volumes with arches and has a grandiose and unique character.

Também conhecida como Igreja Matriz da Arrentela, foi construída no século XV, mas a sua reconstrução, após o terramoto de 1755, conferiu-lhe um estilo predominantemente barroco. O seu interior, de uma só nave, é revestido por uma série de painéis de azulejos do séc. XVIII, representando cenas da vida da Virgem. No exterior, o miradouro proporciona uma vista fascinante sobre a baía do Seixal.

A church with one sole nave and frescoes of the 16th and 17th centuries that show angels with incense, dressed in the 1500s fashion, and also a group of images related to the life of Jesus.

The chapel, which burned in 1895, has very simple lines, with a masonry portal and an opening on the fronton, composed of a high altar and a sacristy. Two different architectural modules can be viewd here. Inside, one can find a John Paul II tile of the 1980s and a Saint Peter of the 18th century.

A small rural temple where the pilgrims come. A special note to its general architectural quality and to the chapel's tiles.

The oldest temple feature is the primitive image of its patron saint - Saint Bartholomew - in calcareous rock (14th century), currently in the parish residence of Santiago do Cacém.
