Mulini di Bulla

In a wooded gorge between Ortisei and Bulla, three stone grain mills document a piece of Alpine industry. Built in the eighteenth and nineteenth centuries, they were worked by village families until the 1970s and are now partly restored.

Why it matters

Grain did not grow easily in Val Gardena, and what little ripened had to be milled somewhere with reliable water power. The answer was the gorge below Bulla, where farm families built and shared mills in the eighteenth and nineteenth centuries. The official Val Gardena portal names three of them: Mulino Droch, Mulino Zaramin and Mulino Rumanon. When milling finally stopped in the 1970s the buildings slid into decay, and what visitors see today is the result of a deliberate rescue — the Rumanon and Droch mills have been restored and are described as partly functional, while only ruins remain of the Zaramin neighbour. As industrial heritage, the site documents a pre-tourism economy of the Ladin valley, when Ortisei's wealth came as much from fields and millstones as from carved wood.

What to notice

The mills exploit the steep gradient of the Bulla gorge. Remains of channels, weirs and penstock lines show how the stream was divided and delivered to each wheel. At the restored Rumanon and Droch mills, gearing, stones and flumes preserve the machinery; the Zaramin ruin retains walls, a wheel pit and collapsed timber.

Context and history

The mills belong to the agricultural substrate that underlies Val Gardena's better-known artistic story. Built between the eighteenth and nineteenth centuries — the event archive of the South Tyrol culture portal records they served to grind grain grown in the area — they were communal infrastructure, maintained by the families who used them rather than by a single owner. Their decline came swiftly once alpine agriculture retrenched after the Second World War: cheap flour arrived by road, and the last grinding ceased in the 1970s. The restoration of Rumanon and Droch forms part of a broader heritage programme with the Ortisei tourist board. The mills and neighbouring rose garden together reflect an agricultural landscape used by the families who built the mills.
