The village lies 12 kilometers from Casale Monferrato, near the Po River. Its name’s origin is uncertain; it may derive from Pons Sturae or Pons Turritus, likely referencing a bridge over the river. Legend has it that in 218 B.C., Hannibal crossed this bridge with his elephants.

The existence of an ancient castle is certain, though no trace remains today. Ludovico il Moro was once imprisoned in its dungeons, and many historical events, both before and after, confirm its presence and use. The castle was demolished by Napoleon, and today a large square occupies its former site.

Several Marquises of Monferrato, including Margherita Paleologa, wife of Federico II Gonzaga, were born here or had summer residences in the village.
The parish church of S. Agata was founded in 1140 and, through countless historical events and changes in ownership, has survived to the present day. It has been modified over the centuries and probably profoundly altered. The brick façade, accented with pale sandstone bands around the rose window, faces a square paved with carefully selected river stones in black and white, arranged by color and size. Inside, the three-nave layout impresses with its scale.
Near the Porta di San Rocco, still within the ancient walls, stands the church of San Giacomo, the first religious building encountered when entering the village. Of medieval origin, it may have been part of a 13th-century hospital and today appears fully plastered, attached to an old palace.

Local culinary specialties are also noteworthy. In the village’s pastry shops and bakeries, one can find the Pontestura cake, a distinctive regional treat made with apples and chestnuts. Another must-try are the sgunfiun, a type of fried carnival pastry similar to bugie.
