The story
The story of Castelguglielmo
In the middle Polesine, between Rovigo and the Po
Castelguglielmo lies in the Polesine hinterland, in an agricultural plain roughly halfway between Rovigo and the course of the Po, in an area where municipalities follow one another in close succession, often blending seamlessly into the landscape. It's a predominantly cereal-farming area, with maize, soybean and sugar beet crops covering much of the municipal territory. There are no natural features of particular note, but the charm of these places lies precisely in their agricultural authenticity, little touched by tourism, and in the chance to discover, village after village, traces of a medieval history often surprising for such a quiet territory today.
The castle that gave the village its name
The first reliable records of this territory date back to the tenth century, when the area was known as Villa Manegii and probably also included nearby San Bellino, with a castle and a church dedicated to San Nicolò. It was Guglielmo III of the Adelardi Marcheselli, governor of Ferrara, who in 1146 had the pre-existing fortification, probably already in ruins, rebuilt and named after himself: Castel Guglielmo. In the Middle Ages, after the Po flood of 1151 and bitter struggles between Guelphs and Ghibellines, the territory passed at the end of the fourteenth century under the Republic of Venice, beginning a phase of economic growth linked to the continuation of the Este land reclamations.
Church, civic tower and Villa Pelà
Castelguglielmo's centre still preserves several notable historic buildings today, starting with the Church of San Giovanni Battista, dating to the fourteenth century, and the civic tower, which offers a panoramic view over the surrounding countryside. Among the monuments are also the sixteenth-century parish church of San Nicola di Bari and the eighteenth-century Villa Pelà, a noble building that today houses a savings bank. It's an unexpectedly rich heritage for such a small municipality, evidence of a past of strategic and administrative importance that today's agricultural landscape wouldn't suggest at first glance.
Agricultural life and the local community
Today Castelguglielmo is a quiet municipality, whose economy remains tied mainly to agriculture and essential village services. Its modest population lives at a pace set by the farming seasons rather than by tourism, and there are neither numerous accommodation facilities nor an entertainment offer comparable to the larger centres of the Polesine. It's fair to present it for what it is: a rural village with a surprisingly rich historical heritage but a simple everyday life, suited to those seeking to know the authentic Polesine rather than a pre-packaged tourist experience.
A starting point for the castles of the Polesine
Castelguglielmo lends itself well as a stop on a route dedicated to the castles and historic fortifications of the province of Rovigo, scattered among the small municipalities of the middle and upper Polesine. Moving by car or bicycle between these villages reveals a territory where the medieval border between Este and Venice, between Guelphs and Ghibellines, has left traces still legible in the local urban fabric and place names. It's a slow way of travelling, little covered by classic guidebooks, that rewards those keen to step off the Veneto's better-known routes.
