History
Castel Sporo, also known as Castel Sant’Anna or Castel Sporo-Rovina, is a medieval castle in Sporminore, Italy, in the region of Trentino. Construction began in the twelfth century, and the fortress guarded the Imperial, or Traversara, road through the Sporeggio Valley, linking the Burgraviato with the Giudicarie and the Lower Sarca. Its position also enabled visual contact with Castel Belfort, Torre della Visione, Castel San Pietro, Castel Thun, and Castel Belasi.
The Sporo family and the prince-bishopric
The Sporo family appears in records from 1165, when Antonio of Sporo took part in a tournament at Zurich. In 1190, Mamelino of Sporo was listed among the followers of Corrado of Beseno, prince-bishop of Trent, who accompanied Henry VI of Swabia to Rome for his coronation. Henry VI was a German king and Holy Roman Emperor whose rule linked the region to the wider politics of the medieval empire.
In 1231, Olurandino of Sporo was described as a knight from the lineage of the Counts of Appiano. This probably reflects the family’s jurisdiction over Castel Sporo on behalf of the counts, who had received it from the prince-bishop. That year, the vassals of Count Udalrico of Appiano in the Non Valley were transferred to the bishop of Trent. A prince-bishop was both a church leader and a territorial ruler, so the prince-bishopric of Trent combined ecclesiastical authority with control of land and fortresses.
Tyrolean control and the rise of the Spaurs
Conflict between the Counts of Tyrol and the prince-bishopric of Trent intensified after the rise of Emperor Frederick II. In 1236, Albert III of Tyrol took Castel Sporo after Prince-Bishop Aldrighetto Campo had been deprived of his principality. Albert’s successors, Meinhard I of Tyrol-Gorizia and Meinhard II, continued Tyrolean expansion. In 1251, they also took nearby Torre della Visione from Prince-Bishop Egno.
The earliest known reference to the castle itself dates from 1276, when King Rudolf I of Habsburg ordered Meinhard II to return properties taken from Prince-Bishop Henry II of Trent, including the Castrum de Spur. Meinhard did not comply, and Castel Sporo remained with the Counts of Tyrol. The last known members of the Sporo family included Svicherio, the castle’s gastald, or territorial administrator, in 1289, and Randolfo, who served as captain in 1304.
In 1312, Volcmaro of Burgstall took possession of Castel Sporo as captain of the jurisdiction of Sporo. His family adopted the Germanized name Spaur, derived from the castle, and took over the red lion on a silver field previously associated with the Sporo family. The original family had exchanged its rights to the castle for Castel Spauregg at Parcines.
Volcmaro’s connection with Henry of Carinthia, count of Tyrol, enabled him to expand his jurisdiction. In 1334, it included Castel Visione and Castel Flavon, and in 1338 it was extended to Nave San Rocco, Fai della Paganella, and Zambana. In the summer of 1342, Volcmaro was besieged at Castel Sporo, captured, imprisoned, and killed at Strassberg fortress in 1343. Castel Sporo, Castel Flavon, and the Rocchetta were then entrusted to Corrado of Scena. In 1346, Volcmaro’s sons Paolo, Baldassarre, Matteo, and Giovanni received renewed confirmation of their possession of the castles and jurisdictions of Flavon and Sporminore.
Conflict in the fifteenth and sixteenth centuries
Matteo and Pietro Spaur, sons of Baldassarre, inherited the castle. Pietro, who lived from 1345 to 1424, was known as “the terror of the Non Valley.” He supported Prince-Bishop Giorgio of Liechtenstein during the conflict between the prince-bishopric and the County of Tyrol under Frederick IV of Habsburg.
After the Council of Constance ended in 1418, Prince-Bishop Giorgio returned to Trent and the conflict resumed. The Council had addressed the Western Schism and other major issues within the church. Because Trent supported Frederick IV, Giorgio took refuge in Pietro Spaur’s castle, where he died in August 1419, perhaps poisoned on the castle owner’s orders. After Pietro’s death in 1424, his sons Giorgio and Giovanni reconciled with Frederick IV and recovered Sporo, Castel Valer, and Castel Flavon, together with the tower of Mezzocorona and the title of grand cupbearer of Tyrol, a prestigious court office associated with serving wine at the ruler’s table.
During the Peasants’ War of 1525, subjects from Flavon, Castel Sporo, and Castel Belfort attacked the castles. The uprising was driven by rural poverty rather than by the religious causes associated with the Protestant Reformation, the sixteenth-century movement that challenged the authority and practices of the Roman Catholic Church. Bishop Bernardo Clesio fled from Trent to Riva del Garda.
On 6 June 1525, Archduke Ferdinand I of Habsburg ordered the subjects of Flavon and Sporo to leave the castles and surrender them as fiefs to the Spaurs. Military action was still needed. In September, troops of the Count of Tyrol and Prince-Bishop Bernardo Clesio forced the rebels at Castel Belfort to surrender. On 21 September, Ludovico Lodron and Francesco Castellalto assembled the subjects at Sporminore and read Ferdinand’s sentence. Except for the revolt’s leaders, the men of the Flavon community and the jurisdictions of Sporo and Belfort had to swear loyalty to Ferdinand and to the dynasts of the three castles, surrender their weapons, and accept the loss of their right to send representatives to the Tyrolean diets. Sporminore was also fined 500 florins, while a garrison of 25 men remained at Castel Sporo to prevent renewed disturbances.
Decline and restoration
In 1643, Giorgio Federico Baron of Spaur and Valer ordered renewal work in the castle’s upper chamber, suggesting that the structure was already deteriorating. It remained inhabited in 1727, but in 1736 Giovanni Battista Spaur asked the co-counts to contribute to repairs. From the eighteenth century, the Spaurs increasingly withdrew to their palaces in the village.
In May 1787, Count Carlo proposed demolishing the castle, which had become uninhabitable because of the lack of water and the poor condition of the roads. He intended the Spaur palaces to replace it as the central residence for the jurisdictions of Sporminore, Flavon, and Belfort, while also taking on the subjects’ maintenance obligations. The castle ruins were restored and opened to the public in 2009.
Remains
Fortified complex
The surviving castle occupies a fortified position associated with the route through the Sporeggio Valley. Its principal structure was a relatively imposing pentagonal keep, forming the core of the defensive complex. Only the first 14 metres of the keep remain, leaving the lower part of the main tower as the clearest surviving element of the castle.
Pentagonal keep
The pentagonal keep was the castle’s dominant structure. Its surviving lower 14 metres preserve the scale and polygonal form of the principal tower, while the upper portions have been lost. Restoration has stabilized the ruins and made the remains accessible.
Curtain wall and enclosed buildings
A curtain wall enclosed the keep together with four towers, residential buildings, and a chapel dedicated to Saint Anne. These elements formed a single fortified compound rather than an isolated tower. The castle’s position also maintained visual connections with Castel Belfort, Torre della Visione, Castel San Pietro, Castel Thun, and Castel Belasi.
