From the Punic sacrarium to the remains of the late Republic and Imperial Roman city, from the 14th-century Catalan-Aragonese churches passing to the 20th century when, after the bombardments of World War II, the medieval district of the Marina and its monuments were restored to new life. The Sant’Eulalia (Mutseu) museum consists of a journey stretching over 2,000 years through the history of Cagliari, especially in the ancient nucleus built near the port, which includes countless monuments - the parish church of Sant’Eulalia, a church dedicated to the patron saint of Barcelona (later enlarged and modernised), the archaeological area below, the Museo del Tesoro, the parish archives, the monumental crypt (16th-17th centuries) and the excavations beneath the church of Santa Lucia. The museum, set up in a building adjacent to the parish, preserves the extensive artistic heritage of the churches of Sant’Eulalia, Santa Lucia and Santo Sepolcro and the archival material of the parish and archconfraternities of the Crucifix and the Holy Trinity, active between the 17th and early-20th centuries.
