Castiglione del Lago
A lakeside town on the former fourth island of Lake Trasimeno, Castiglione del Lago evolved from a Roman outpost into a Renaissance marquessate under the della Corgna family, who transformed it into a centre of artistic and intellectual patronage.
At a glance
Castiglione del Lago occupies a hilltop site overlooking Lake Trasimeno. The town’s name derives from Castellum Leonis, the Castle of the Lion, which featured in the coat of arms of its medieval rulers. Its strategic location between Orvieto, Chiusi and Arezzo made it a contested frontier zone across millennia.
History
The Romans founded the settlement as Novum Clusium (New Chiusi). The three parallel streets that traverse the town preserve its Roman grid pattern. What was once the fourth island of Lake Trasimeno, separated by water from the mainland, became joined to the shore over centuries.
After Roman rule, Castiglione endured repeated destruction and rebuilding, caught between competing powers. Frederick II’s reign at the start of the 13th century brought temporary stability. By the late medieval period, Perugia controlled the town as part of the Baglioni family’s domains.
In 1550, Pope Julius III granted the fiefdom to his sister Giacoma Ciocchi del Monte. On 19 November 1563, her son Ascanio della Corgna became Marquis of Castiglione and Chiusi by decree of Pius IV, alongside his brother, Cardinal Fulvio. Paul IV elevated Fulvio II to duke in 1617. When Duke Fulvio II died in 1647 without heirs, the fiefdom reverted to the Papal States.
What you see
The urban layout preserves evidence of its Roman origins in the decumani—three longitudinal streets that divide the town. The Renaissance palace designed by Vignola and Galeazzo Alessi showcases frescoes by Pomarancio and other painters. The palazzo served as the marquis’s residence and venue for the Accademia degli Insensati, hosting intellectuals and artists.
Cultural significance
Under Ascanio I and his successors, Castiglione became a centre of Renaissance culture and learning. The marquessate exercised imperial powers within papal territories, including the right to mint coins. Ascanio della Corgna issued comprehensive civil and criminal statutes in February 1571, later refined by Cardinal Fulvio and Duke Diomede. The court attracted the burlesque poet Cesare Caporali and the political theorist Scipione Tolomei. The marquisate functioned as a strategic buffer zone between the Grand Duchy of Tuscany and papal lands, covering approximately 200 square kilometres.
