The Aurea Palacio de Sober 4* is the largest civil building in Galicia. The original construction consisted of a medieval tower in the 12th century, pertaining to the López de Lemos lordship, the Lords of Sober and Ferreira. The present building is a reconstruction carried out in 2010, which shows the different historic eras and includes the remains of a wall from the 12th century.
The lineage of the Lords of Sober and Ferreira dates back to the reign of King Alfonso I of Asturias (known as the Catholic, 739-757), or the Reconquista period that was marked by Islamic raids. Lope López de Lemos built the first construction in Sober, which was related to important families of the Galician nobility.
The Palacio de Sober is a historic landmark, having been the setting for the Irmandiña revolts, among other historic events. In 1467, their leader, Diego de Lemos, rose up against the high nobility, destroying his father's palace.
Legend has it that Fernán López de Lemos added twelve roundels to the one featured on his lordship's coat of arms after rescuing twelve maidens from the Moors. The coat of arms with thirteen roundels can be seen in several rooms at the hotel.
