The building has a single nave with a rectangular plan. The apse is oriented to the N-E, with an apsidal vault cover and a lantern of wrought iron and glass based on paraboloids and hyperboloids.
The material used is rustic stone with some elements of polychrome glass and glazed tiles. The two-sided roof is made of Arabic tiles. A small, attached bell tower is crowned by mosaic, establishing a certain link with the project of the estate of Josep Puig i Cadafalch. The access, located on the side, is preceded by a porch with three arcades, the rhythm of which recalls a Florentine loggia.
This chapel, which is part of the property of Can Garí del Cros (house built by the architect Josep Puig i Cadafalch), was already mentioned in 1187, but it was ruined and only a stone cross with relief, a piece of cornice and a square foot of terracotta are preserved. In 1929, Lluís Bonet i Garí designed a new church.
The documentation on the hermitage is mainly due to Carreras Candi, who explains its existence through the document of 1187. The oldest location is from 1323; there is another, from 1385, in favour of Joan de Caldes due to Bernat d'Agell's renunciation of the benefit of the altar of Sant Miquel del Cros. Around 1884, the Romanesque chapel was demolished and a new one was built, according to Domènech i Estapà's project, which was demolished in 1926, after which the current one was built.
From very early on, Bonet Garí collaborated with Josep Puig i Cadafalch, the author of the remodeling and restoration of Can Garí. At the same time, the admiration he felt for Antoni Gaudí also led him to use some of the solutions in this hermitage.
Currently, the small chapel does not have regular worship and the Garí family gave it to the bishopric, and it depends on the parish of Sant Julià. Once inside the property, a path from the Can Garí entrance leads directly to the hermitage and has a small fence that separates it from the garden area.
Small rectangular nave, with the apse oriented to the N-E, covered with an apsidal vault and lantern of wrought iron and glass based on paraboloids and hyperboloids. The access is through a side porch. The façades are finished in exposed stone, with decorative elements based on polychrome glass and glazed tiles.
The original Romanesque church was demolished in 1884 to build a new one, which was demolished again in 1926. Some fragments of the original chapel still remain, such as a stone cross with relief, a piece of cornice and a square foot of terracotta.
It is currently located within the estate of Can Garí del Cros, surrounded by the estate's own fence, apart from its own, of wrought iron.
