Maccastorna Castle, Medieval castle in Maccastorna, Italy.

Maccastorna Castle, also called Belpavone, is a military structure built in the 13th century on an irregular quadrangular plan near the right bank of the Adda. Of the original layout, a portion of the perimeter walls survives.

Built in the 13th century by Ghibellines expelled from Cremona, the castle stands near the right bank of the Adda. From 1272 to 1381 the Vincemala family held Mero e Misto Impero over Maccastorna and neighbouring lands. In 1371 Gian Galeazzo Visconti acquired it and in 1385 gave castle and fief to Guglielmo Bevilacqua. In the 15th century Cabrino Fondulo added the walls, moat, drawbridge and prisons; the Bevilacqua held it until 1901.

The castle's name Belpavone may derive from a local noble title, and the site is tied to the Vismara family, who held the Mero e Misto Impero over Maccastorna and five neighbouring villages from 1272 to 1381. A local tradition holds that the cries of guests killed in 1406 still echo in the halls.

The castle stands in Maccastorna, on the right bank of the Adda in the province of Lodi. Of the original structure only a section of the perimeter walls survives, so look for the remaining masonry rather than a complete circuit. The site is private property and the sources give no opening times or visitor facilities; check locally before travelling.

The castle is also called Belpavone. Its name is tied to the 1406 dinner: Cabrino Fondulo had his guest Carlo Cavalcabò and his retinue killed after the meal and thrown into the castle's well, the pozzo delle taglie. Local tradition holds that their cries still echo in the halls.
