The Bogna is an Alpine torrent of the Ossola in northern Italy. It flows through the Val Bognanco (to which it gives its name) and into the river Toce [1] near the city of Domodossola as a right tributary. The river starts at Monte Bardo, has a length of about 12 miles, and is known as an "unjust river" (Italian : iniquo fiume) for the destructive floods it had caused in Domodossola for centuries. [2] [3]
As the river runs through the entire Bognanco Valley and crosses the municipalities of Bognanco, Domodossola and Crevoladossola. A 1,300 m-long (4,300 ft) wall, the muraccio, was built in the late 18th century to protect the city of Domodossola from the floods of the river. [3] In the 19th century, a remarkable bridge,[ which? ] a masterpiece of architecture, stood over Bogna. [1]
