Brich di Zumaglia, Mountain summit in Piemonte, Italy

Brich di Zumaglia is a 669 m hill in the Biella area, on the land of Zumaglia and Ronco Biellese. It has twin rounded, wooded summits separated by a 620 m saddle; the name brich denotes rough terrain. The castle of Zumaglia stands on the top, surrounded by a park with rare and exotic trees.

A fortress was constructed at the summit in 1291 and has defined the site ever since. The structure was nearly destroyed in the 16th century and then extensively rebuilt in the 20th century.

The name Zumaglia comes from zumaja, a Biella dialect word for breast, describing how the twin hills look from a distance. Brich is a term for rough, uneven terrain. The castle on the summit hosts exhibitions, receptions and a summer travelling theatre festival staged by the company A.R.S. Teatrando.

The Brich is reached from the A4 Turin–Milan motorway, exit at Santhià, then along the SS 143 to the turn-off for Ronco Biellese. Inside the park, woodland trails and cobbled roads total about 4,000 metres, crossed by the GtB long-distance route. The two hills are joined by a wooded saddle at 620 m.

The castle park holds rare and exotic trees of notable size, while the dense chestnut woods covering Mont Prève are the typical growth of the Biella hills. The two hills are joined by a wooded saddle at 620 m, and about 4,000 m of woodland paths and cobbled roads cross the park.
