The church lacks a crypt, which was common in other Asturian pre-Romanesque structures.
The mural paintings were executed using the 'buon fresco' technique with a sophisticated color palette including ochre, red, and blue.
The floor plan features a unique iconostasis that physically separates the clergy from the congregation.
Evidence suggests the church was once connected to a royal palace via a porticoed walkway.
The masonry incorporates repurposed Roman stone materials, known as spolia.
The frescoes contain no human figures, focusing instead on decorative architectural vistas and geometric patterns.
Archaeological excavations have uncovered fragments of original mosaic floors underneath the current surface.
The church was designed with an open chamber or 'tribune' above the vestry, likely reserved for the monarch.
Iglesia de San Julián de los Prados, also known as Santullano, is a pre-Romanesque church commissioned by King Alfonso II of Asturias in the early 9th century. It is the largest and best-preserved monument of the Asturian pre-Romanesque architectural period. The interior houses an expansive collection of original 9th-century frescoes, the most significant mural cycle of the early Middle Ages in Spain. These paintings represent architectural motifs rather than religious figures, deviating from the typical iconography of the era. The structure is built with a tripartite chancel and features a vaulted ceiling. Its design reflects the influence of the Roman world, specifically the villas of the late Roman Empire. It is a UNESCO World Heritage site as part of the Monuments of Oviedo and the Kingdom of the Asturias. The church occupies a site once part of a larger palace complex intended for royal use. Its state of preservation provides unique insight into the artistic transition from late antiquity to the Medieval period in the Iberian Peninsula.

Use the audio guide provided at the entrance to understand the complex symbolism of the abstract mural paintings.
Check for temporary visitor restrictions, as the delicate state of the frescoes occasionally limits access to certain areas of the interior.
Avoid using flash photography, as high-intensity light can damage the centuries-old pigments.
Do not attempt to touch the walls or frescoes, as the oils from skin cause irreversible damage to the medieval layers.
Closed to the public on Mondays throughout the year.
Maintain a quiet, respectful tone; photography is permitted but strictly without flash.
