===Ancient times===
There still remain traces proving the existence of settlements in this municipality in a time prior to the arrival of Romans. Although it is supposed that there were already populated enclaves in the area during the [[Paleolithic]], there are no remains of this time, so such a supposition could not be demonstrated. Nevertheless, remains of the [[Neolithic]] have reached up to the present day. For example, several burial mounds were found in the mountain range of [[Penouta]] in what is one of the vastest burial mound fields in the whole Asturias, with 72 catalogued tombs. Likewise, [[dolmen]]s near [[Llaviada]] (nowadays disappeared) are supposed to date from this time, together with the oscillating granitic mass known as [[Penedo Aballón]] (located near Penouta, and knocked down in 2004, probably by a few vandals).

From the [[Bronze Age]] (approximately 1500-1100 b.C) are believed to date the anthropomorphic paintings (both masculine and feminine) found in the [[Cova del Demo]] ("Cave of Devil" in English), located near the hamlet of [[Froseira]], in the civil parish of [[Doiras]].

All the preceding facts, together with the signals of mining work devoted to the extraction of metals and, especially the [[Celtic fortifications]] of [[Pendia]], [[Los Mazos]] and [[La Escrita]] also prove the aforementioned pre-Roman settlements.
The subsequent [[Ancient Rome|Roman]] presence, after the conquest carried out by the legions under command of General [[Publio Carisio]] (the X Gemina and the V Alaudae), left imprints such as several coins and [[ceramic art|ceramics]] fragments, as well as probably the origin of the names of some small villages such as [[Vega de Ouria]], likely due to the presence of some river [[gold]] working in that time. In those days, it is believed that the area corresponding to the civil parish of [[Castrillón]] was populated by the astur tribe of [[Pesicos]], whereas the area located western from the [[Navia River]] would have been inhabited by the gallaeci tribe of [[Albions]].

After about four centuries of Roman domination, the barbarians entered the Iberian Peninsula, and [[Suebi]] settled down in the western area of Asturias, reaching their maximum expansion about the year 450. It is known that later arrived [[Visigoths]], that occupied the whole territory about 584. However, there are very little archaeological remains of all those populations.
