The Merse is a 68 km long river in the Tuscany region of Italy, which crosses the provinces of Siena and Grosseto from north to south and flows into the Ombrone at Pian di Rocca (district of Monticiano ) as a right tributary .

course

The river has its source in the Poggio Croce di Prata and Poggio di Montieri hills south of Montieri in the Colline Metallifere range of hills at an altitude of 848 m and spends 8 km in the municipality. It flows past the old mines of Montieri, called Le Roste because of their oxidizing iron minerals and copper residues , and turns first northeast towards Chiusdino (18 km in the municipality). He passes the district of Ciciano , southwest of Chiusdino, and then the district of Palazzetto , to the southeast . It then flows north past the Abbazia San Galgano , which it served as the main source of water in the Middle Ages, where after a few kilometers the Fèccia river joins the Bivio del Madonnino as a left tributary . From there the river runs a few kilometers to the east, then to the north, where it flows around the districts of Sovicille (18 km in the municipality) Brenna and Orgia . Here the river turns to the south, where it passes at San Lorenzo a Merse , a district of Monticiano (14 km in the municipality) and undercuts the Strada Statale 223 di Paganico . From there to the mouth it serves Murlo as a western border (7 km). A few meters afterwards, he passes the Ponte a Macereto bridge (also called Ponte a Maciareto ), which was built in 1368 and used until 1827, and which today can only be viewed as a ruined bridge. The bridge was rebuilt in 1487 under the direction of Francesco di Giorgio Martini after it collapsed in large parts due to floods in the spring of 1485. After the construction of the new bridge for the Regia Strada Grossetana in 1827, it was no longer used and suffered damage in the Second World War . The current situation was created by the floods of 1962. Behind the district of Bagni di Petriolo , the Merse meets its right tributary, Farma . A few kilometers further on, it flows into the Ombrone in the Pian di Rocca district , of which it is the right tributary.

The former covers approx. 2000  hectares , the latter approx. 1743, both of which are in the province of Siena, the Basso Merse Nature Park also in the province of Grosseto (1,478 hectares in the province of Siena, 265 hectares in the province of Grosseto).
