The hermitage has been documented since the end of the s. IX where in a parchment from the chapter archive of the headquarters of Barcelona it mentions the current hermitage under the name "parróquia de Santa Madrona". However, in the 14th century the dedication changed to Sant Pere and is currently dedicated to Our Lady of Health.
It is a simple construction, with very little decoration, but in an excellent state of preservation. The building was initially a single nave, with a possible quadrangular head and a wooden roof dating from the s. X. In an extension to the s. In the 11th century, a triple head with a semicircular apse and two apsidioles on the sides, a barrel vault with fascinted arches was added and the nave was enlarged, becoming longer and, possibly, higher.
The buttresses are evident on the outside. At the feet there is an interesting twin window with a capital of acanthus leaves on a small column, few of which are preserved in pre-Romanesque architecture. The central apse has Lombard arching and pilasters typical of Catalan Romanesque architecture. In addition, the central door, also built in the s. XI, presents a porticoed door decorated with a half-point arch inscribed on the wall that generates a tympanum today without decoration.
