In the 13th century, the Pisan count Ugolino della Gherardesca ruled Sardinia's silver mines with an iron fist
The Silver Ledger — Uncover Count Ugolino's Hidden Vein
You are Ugolino della Gherardesca, the Pisan Count of Donoratico, in Iglesias in the late 13th century.
Your silver mines brought prosperity to the region, but
Delve into the medieval intrigues of Iglesias, a Sardinian city shaped by silver and Aragonese ambitions of the 13th century.
The story that haunts this land
Your quest begins at Castello di Salvaterra, a defensive fortress built in the 13th century by the Pisans, then remodeled in the 14th century under Aragon. Initially called 'Castello di Iglesias', it was renamed Salvaterra in 1324 by King James II of Aragon in homage to his wife. This rectangular structure, approximately 45m x 35m, with its cylindrical towers at the southeast and southwest corners, was restored in 1908 by Florestano Di Saba to become the seat of the archaeological museum. It is here, among the Nuragic and Punic artifacts of Sulcis, that you discover the first clues left by the first bishop of Iglesias, Pietro d'Arboras.
Continue towards the Cattedrale di Santa Chiara, consecrated in 1288 by Pope Nicholas IV, marking the first bishopric of the Kingdom of Aragon in Sardinia. Built in Gothic-Catalan style with Pisan influences, its single nave, 20m long, houses the silver statue of Santa Chiara (1677) and 14th-century Gothic frescoes. The original 13th-century ogival portal, despite 18th-century Baroque alterations, testifies to its deep history. In 2017, Pope Francis elevated it to the rank of minor basilica. Here, hidden symbols in the stones guide you through the secrets of the medieval city of Iglesias, an essential site for the Sistema dei siti nuragici UNESCO.
Your journey then leads you to Piazza Sella, Iglesias' main square, a nerve center since the 13th century. It was named after Quintino Sella, the Italian minister who, in the 19th century, spurred local mining, making the square a place where silver and sulfur were traded as early as 1300. Surrounded by neoclassical buildings linked to mining administration, this square is a convergence point for the city's main historical monuments. The Mura Pisane, with Porta Nuova, the sole survivor of the 13th-century ramparts and restored in 2003, reveal messages carved into the stone, uncovering clues about Ugolino's secret ledger.
Exploring the city of Iglesias, you discover the Palazzo Civico, built in 1838-1840 in a neoclassical style. This municipal seat, with its monumental 28m wide facade, Doric columns, and triangular pediment, houses interior frescoes by Giovanni Marghinotti dating from 1842. In 1861, it hosted the first post-unification assemblies of Italy in Sardinia and was classified as a national monument in 1935. Nearby, the Chiesa di San Francesco, founded in 1265 and rebuilt in 1725, with its 42m bell tower, the tallest in Iglesias, offers a perspective on the mining communities, loyal to this site of annual procession since 1650.
Your investigation concludes near the Fontana di Piazza Lamarmora, erected in 1882 in honor of King Vittorio Emanuele II. Its octagonal basalt basin, 6m in diameter, and bronze sculpture by Romualdo Prini, fed by the Fontanas de Sa Duchessa source, were the center of popular festivities linked to the San Luca silver mine. By exploring these places in Carbonia-Iglesias, you have deciphered Count Ugolino's secrets, discovering the silver ledger that sealed his power. You have explored Iglesias, one of the Borghi più belli d'Italia, and you carry not only the satisfaction of having solved the enigma but also a deep understanding of its mining and medieval heritage, a true thematic circuit that enriches your visit to Iglesias.
