Molina de Aragón is a municipality located in the province of Guadalajara, Castile-La Mancha, Spain.

It held the record (−28.2 °C) for the lowest temperature measured by a meteorological station in Spain, and now it is in third place.

[2] It was the seat of the taifa of Molina, a Moorish independent state, before it was reconquered by the Christians of Alfonso I of Aragon in 1129.

On 21 April 1154 Manrique Pérez de Lara issued a sweeping fuero to the town of Molina, which he was building into a semi-independent fief.

Winters are cold for Spanish standards, with temperatures often below 0 °C (32 °F) due to its altitude and its inland location.
