Museum of the Treasure and Archaeological Area of Sant’Eulalia
The Museum of the Treasure and Archaeological Area of Sant’Eulalia is a remarkable dual-level heritage site beneath and within the church of Sant’Eulalia in Cagliari’s historic Marina quarter. Below the church, a glass-floored walkway reveals a stratified archaeological excavation exposing Roman roads, drainage channels, and medieval structures; above, the museum displays a rich treasury of liturgical silver, sacred art, and devotional objects accumulated over six centuries of parish life.

Overview
The complex occupies the church of Sant’Eulalia, one of the oldest surviving Gothic churches in Cagliari, built in the 14th century in the heart of the Marina district — the mercantile quarter that once housed Cagliari’s most prosperous traders. Excavations carried out during structural works revealed an extraordinary sequence of archaeological remains beneath the church floor, including a well-preserved Roman street with flanking structures and later medieval layers. The museum integrates the treasury display with the underground archaeological area, creating a layered journey through 2,000 years of urban history.
History
The church of Sant’Eulalia was founded in the 14th century under Aragonese rule, replacing an earlier place of worship in the commercial heart of Cagliari. Over subsequent centuries the parish accumulated an exceptional collection of liturgical silver, embroidered vestments, paintings, and devotional objects donated by the wealthy merchant families of the Marina. Archaeological investigations in the 1990s–2000s uncovered the Roman layers beneath the church, including sections of the ancient street grid of Caralis (the Roman name for Cagliari), which the museum now presents in situ beneath glass walkways.
What you see
The underground archaeological area presents Roman cobbled streets, drainage channels, column bases, and structural walls visible at close range through glass floors and open trenches with interpretive panels. The treasury museum above displays silver chalices, monstrances, processional crosses, reliquaries, and embroidered liturgical textiles ranging from the 15th to the 20th century, many of outstanding craftsmanship from Iberian and Sardinian workshops. The Gothic church interior itself retains original 14th-century fabric including carved stonework and vaulted bays.
Cultural significance
The Sant’Eulalia complex is unique in Cagliari for combining a Roman archaeological area with a significant ecclesiastical treasury within a single living heritage site. It demonstrates the continuous occupation and cultural stratification of the Marina district across two millennia and is one of the most visited heritage attractions in the city. The treasury is recognised as one of the finest collections of Sardinian and Iberian liturgical silverwork in the region.
