Larrosa

Larrosa is an unpopulated settlement and a former municipality of Spain, belonging to the present municipality of Jaca, in the comarca of Jacetania, province of Huesca, Aragon.

Geography
Larrosa is located at the head of the valley of the Ijuez river, a tributary of the Aragon river, in the valley of the Garcipollera, like Acín, Villanovilla, Bescós de Garcipollera and Yosa de Garcipollera.

History
The houses and fields of the municipality of Larrosa were expropriated in the 1960s, due to the construction of the Yesa Reservoir, in order to use their forests for planting pine trees to prevent the rapid silting of the new reservoir by the sediments carried by the rains.

The church dedicated to San Bartolomé has well preserved its Romanesque structure.
