At the top of Mount Cinto are the ruins of an ancient medieval fortification, now hidden by vegetation. The castle, small in size and oval in shape, had walls and buttresses and was part of a defensive system likely connected to the church of Cinto Euganeo, serving a strategic control function over access to the Euganean Hills.
Already documented around the year 1000, in the 12th-13th century it passed to the De Lendinara family, then it was occupied by Ezzelino da Romano, and in 1275 it became a garrison of the Municipality of Padua with a small local garrison. During the Carrara period, it was further used to defend the territory from the Scaligeri. With the arrival of the Republic of Venice, it gradually lost importance and was abandoned between the 15th and 16th centuries.
During World War II, the area was reused by the Germans with trenches and posts. Today, traces of the walls and an ancient stone mortar remain, a testament to the various phases of use of the site over the centuries.
