The municipality was created in 1973 by merging the communities of Bolea, Esquedas, Lierta, Plasencia del Monte and Quinzano.

[2] La Sotonera is 165.5 km2 in size, including a small exclave to the south-west of Banastás and Alerre.

The village of Bolea is the main settlement in La Sotonera and is well known for its Collegiate Church which was declared a National Monument of Historic and Artistic Value in February 1983.

[5] La Sotonera has one railway station at Plasencia del Monte which is on the RENFE-operated line from Huesca to Jaca and Canfranc.

Despite its name, the large reservoir known as Embalse de La Sotonera lies outside of the municipality to the south-west.
