Ponte Alidosi


Andrea Gurrieri built the Alidosi Bridge over the Santerno River in 1499, on Obizzo Alidosi's order.
Apart from connecting the two banks, it was a symbol of the Alidosi family's sway. It is a masterpiece of civil engineering as confirms a local saying: "There is only one Pope, only one God and only one Castel del Rio's bridge".
It is a humpbacked and single-span bridge stretching along 42 m and rising 19 m.
The bridge's abutments contain a few different-sized rooms with a defensive function.
The bridge underwent various changes: in 1642, in 1698-99 and in 1725 to repair the damages provoked by an earthquake. Lastly, it was restored and strengthened in the 50s. It has been national monument since 20 November 1817.
