Tura Bridge, also known as Steccaia and built in 1829 on the right bank of the Ombrone River, is one of the many hydraulic works between Grosseto and Castiglione della Pescaia which offer significant material evidence of a phase of reclamation of Maremma, mostly promoted during the Lorraine period and carried out by worthy scientists and technicians.

By means of the appropriate machinery, Steccaia made it possible to manoeuvre the complex system of sluices and floodgates along the final tract of the Ombrone River and regulate its waters, thereby making it possible to recover land to destine to agriculture.

Despite its present precarious condition, the monumental structure of Steccaia with its hydraulic works and fascinating architectural features still evokes the daring technical undertaking which, with great efforts, led to the successful reclamation of the area.
