The towers are the visible remains of the fortress ordered in 920 by the Bishop of Adria and finished in 954.
Under the direction of the Este family in 1160, the walls and the donjon together with eight other towers and the perimeter moat completed the castle. Torre Donà and Torre Grimani today make up the remains of the walls of Rovigo Castle. They are included in what is now the garden of Piazza Matteotti. A visitable heritage with 1100 years of history. The Donà Tower (named after the family who later owned the property in 1598) is the tallest of its kind in Italy at over 51 metres.
The Grimani Tower (named after the successive owners of the Donà family from the mid-19th century), also known as the Torre mozza, is the headquarters of the CTG Cultural Heritage Volunteers group.
