Remarkable architecture and exterior
Façade and exterior decorations
The western facade of the Cathédrale des Pommiers immediately caught our eye, with its imposing sobriety typical of 12th-century Romanesque art. We paid particular attention to the semi-circular portal featuring three elegant voussoirs supported by finely sculpted colonnettes.

You’ll notice the Lombard details that enrich the architectural ensemble, testifying to the Italian influences in this region. The luminous oculus above the gate adds a touch of elegance to this harmonious composition, creating a subtle play of light that varies according to the time of day.

Bell tower and history
The history of the bell tower of the Cathédrale des Pommiers reminds us of the turbulence of the Wars of Religion that marked the 16th century. We learned that the old bell tower, destroyed in 1564, bore witness to the building’s original grandeur. The current belfry, rebuilt in the 17th century, takes a more discreet approach, contrasting with the imposing original tower.

You’ll discover in this reconstruction the expression of an era marked by prudence, when religious architecture had to balance spiritual affirmation and preservation in the face of conflict. This architectural transformation perfectly illustrates the resilience of religious heritage in the face of the trials of history.
Chapels and extensions
The addition of side chapels to the Cathédrale des Pommiers reveals the evolution of religious architecture over the centuries. We have observed how the five chapels added to the south and the three to the north blend harmoniously into the original Romanesque structure, despite the destruction of the cloister that preceded their construction.

You’ll notice that these extensions feature a variety of alignments and depths, creating a distinctive architectural rhythm that enriches the building’s silhouette. This adaptation testifies to the continuing vitality of the religious community and its ability to adapt the sacred space to suit liturgical needs, while respecting the integrity of the original Romanesque work.
Interiors and treasures to discover
As we entered the Cathédrale des Pommiers, we were struck by the sheer size of the central nave, with its barrel vaulting, a technique typical of late Romanesque architecture. The generous width of this space contrasts harmoniously with the narrowness of the surrounding aisles, creating a perspective that naturally guides the eye towards the choir.

You’ll appreciate the bright, sober ambience that reigns in these uncluttered volumes, particularly conducive to contemplation. The alternation between the shadows of the aisles and the light of the main nave creates a soothing visual rhythm, testifying to the mastery of the Romanesque builders in the art of creating spiritual spaces imbued with serenity.

Apse and dome
The cathedral’s central apse, vaulted in the Romanesque cul-de-four tradition, is the architectural jewel in the crown. We were particularly impressed by the side absidioles, adorned with sculpted shells – remarkably fine decorative details that testify to the refinement of Provençal Romanesque art.

You’ll also discover the trumpeted cupola that marks the entrance to the choir, built on an imposing octagonal mass. The subtle alternation of dark and light stones in this construction creates a striking chromatic effect that underlines the liturgical importance of this space. This natural polychromy, the result of a judicious choice of local materials, lends the ensemble an exceptional visual richness.

Historic furniture and organ
The Merklin organ, installed in 1888, is a veritable heritage treasure at the Cathédrale des Pommiers, with 17 stops on 2 manuals and a pedalboard. We were impressed by the quality of preservation of this instrument, which continues to resonate at celebrations and concerts.

You’ll experience how this period furniture, perfectly integrated into the Romanesque architecture, creates a temporal harmony that unites the different periods in the building’s history. This continuity in liturgical design testifies to the constant vitality of this place of worship over the centuries.

Frequently asked questions
Why is it called the Cathedral of the Apple Trees?
The name “Cathédrale des Pommiers” originates from an alteration of the Latin word pomerium, which in ancient times referred to the open space between ramparts and dwellings. As the cathedral was built in this area in Sisteron, its name has remained associated with this term, gradually deformed into “apple trees”.
