Celanova arises for the history of altomedieval Galicia like social establishment in the first third of century X, at the moment at which Rosendo Gutiérrez Eiriz, a Galician nobleman become related with the kings of Leon and direct descendants of the Asturian real dynasty that had exerted of bishop of Mondoñedo, Iria and Dumio, as well as of governor of the Galicia of its time, decides to carry out a monacal foundation choosing the denominated place of “Villare” that had received in property by donation of its Froila brother and the wife of this one Sarracina and that later would be enriched of very important form by the parents of, Gutier Menéndez and Ilduara Eiriz.

In this place in which the properties were based that Froila and Sarracina had donated to Rosendo stops in which in him it raised a monastery that was to denominate itself as of that moment “Cellanova” and in where had constructed only one old church dedicated to San Martin, is in where Rosendo Gutiérrez decides to construct to that same 936 year an initial set of houses for some thirty monks, next to small oratorio that would be dedicated to arcángel San Miguel, as well as the church with three chapels for its dedication to the cult. Buildings, these, of which graphical certainty is not had some, although yes a suggestive affirmation of own San Rosendo, that in its testament says: “I leave a built house wonderfully You”. 

This oratorio, the one of San Miguel, architectonic tipología mozárabe or restoration, with its arcs of gallonados horseshoe and his modillones. It is the only construction that it connects to us with the original moments of Celanova and that is conserved at the present time, since the first conventual set, studied at its moment by the medievalista Jose Miguel Andrade Leached ashes, would be replaced with the passage of time by a greater building, of the one than any graphical registry is not known either.

Of this building, of style probably Romanesque if it is known, nevertheless, some literary testimony like the one of the historian of the Santiago Apostle, Mauro Castellá Ferrer, who in his chronicle on San Rosendo says: “I reached to see some pieces of which now she is rebuilt again. The grandor of the cells would be of fourteen feet in length and the same in wide, its altor one was average state and, little more, than as soon as it would reach two, the red and white ceiling painted of. (…) The church with the tower greater than for old is very great, beautiful, and of very good crowned vault everything of battlements and saeteras, that seemed soldier and horseman well”.

With the definitive incorporation of Celanova at your service of San Benito at the beginning of century XVI, the building continues growing in wealth and dimension beginning to construct the present factory in which some of the most outstanding authors of the time would participate, like Melchor de Velasco, Castro Canseco, Juan de Badajoz or Plácido Churches. 

Then, the evolution of these three buildings, along with the transfer of properties, as well as the commercial flow that throughout the centuries was generated around to his, were the origin of a social establishment that today continues taking the name of Celanova and that lived its urban appearance from the confiscations on the first third of the century XIX, that is when an important mass of civil populace, that is to say, nonmonacal or of services of the monastery, it begins to acquire properties in the environs of that crossroad in which the monacal building was located, and to evolve towards a commercial villa with exercise of capitalidad of a region that historically it had also evolved according to the beats of the rosendiano monastery.
