Bosco Fontana Nature Reserve, State nature reserve in Province of Mantua, Italy.

Bosco Fontana Nature Reserve is a state protected area in the Province of Mantua, set in a stretch of marshy woodland close to the Mincio River. The forest is made up of mixed trees including turkey oaks, pedunculate oaks, hornbeams, limes, poplars, elms, and alders.

The first historical mentions of Bosco Fontana date to the 14th century. Between the 12th and 13th centuries the Gonzaga, future lords of Mantua, acquired a large estate between the Mincio, Goito and Marmirolo, covered by dense forest rich in game, and turned it into a hunting reserve. Their protection measures kept this stretch of Po Plain forest intact; the hunting lodge inside was built for Vincenzo I Gonzaga and declared a national monument in 1921.

The name of the reserve comes from the Fontana, a spring that rises near the hunting lodge and has been known since the 12th century, when the Gonzaga bought this estate. The lodge itself, built for Vincenzo I Gonzaga to designs by Giuseppe Dattaro, was declared a national monument in 1921.

The forest can be explored on foot along several straight paths that cross it in geometric patterns. The paths are easiest to walk during the warmer months, when the ground is less wet and more accessible.

This reserve protects one of the last remaining patches of the original Po Valley landscape, before farming transformed the region. Natural springs near the hunting lodge feed a local water system that keeps the woodland wet year-round.
