Inside, the plan is basilica, rectangular, with three naves, the central one covered with a pointed vault, supported by pillars and the lateral ones, by reinforced quarter-circle vaults with toral arches.

The famous Christ of Salardú, a Romanesque carving from the 12th century, presides over the main altar, with recently restored fresco paintings. It is the work of the same author of the Christ of Mitgarán.

Once we enter the interior, we are surprised by an elegant Gothic architectural structure supported on pillars with a square base and ribbed vaults. Moving towards the presbyterial area, we come to one of the most extensive and best preserved wall paintings in the Val d’Aran. These are works from the 17th century where various personalities and biblical examples are represented.

The culmination of the visit to Sant Andrèu de Salardú takes place when approaching the central apse, where the majesty carving of the Christ of Salardú is erected, a masterpiece of d’Erill la Vall workshop, to which the execution of the Christ of Mijaran is also attributed. The carving from the 12th century shows the image of a suffering Christ, with the triangular section of the legs and the characteristic features of Romanesque religious iconology.

The bell tower is a tower with a square base and a pyramidal roof. It has a nave that once had a canyon vault, with two chapels on each side and with preserved former arches. The altar altar is an old stone block decorated in the pre-Romanesque style. The veneration of a Renaissance image of the Virgin in a chapel in the presbytery stands out.

The presence of mural painting does not end here, since samples belonging to the 16th century have recently been discovered and restored where, based on the sequence of scenic framings, the episodes take place Biblical images of Jesus’ prayer in the garden of Jethsemane, the kiss of Judas, the scourging, Pontius Pilate washing his hands, the road to Calvary, the Crucifixion and the Last Judgment with the Glorified Christ.

THE Romanesque legacy of the church of Santa Eulària is also revealed through the presence of its baptismal fonts.

The bell tower (from the 17th century), isolated on the east side, has been built in masonry and the corners have been reinforced with stonework. In the upper part there are rectangular and semicircular openings, and under the eaves there are decorated corbels. The altar is Baroque and preserves a foot of a previous one in Romanesque style. It also has a Romanesque baptismal font and a magnificent pictorial panel from the 17th century.

At the west end there is a five-story bell tower with a pyramidal roof that, due to its mixture of Romanesque and Gothic styles, could have been built in the 13th and 14th centuries.

The imprint of the Gothic period in Santa Maria de Arties was masterfully exposed in the mural paintings represented on the ceiling of the presbytery and in the execution of an altarpiece recently restored by the Service of Conservation of Movable Property of Sant Cugat. The altarpiece, originally from the 15th century, represents different biblical scenes of the Virgin Mary and is a masterpiece of Gothic painting.
