House with gallery, Villamayor

An attractive old gallery house in Villamayor, some 100 metres from the medieval convent of St Mary, from which allegedly a number of corbels and perhaps other features were taken in its building. Part of the old convent has been restored and is incorporated as a historical record into the Villamayor town hall. It includes capitels and corbels from, probably, the 12th or 13th centuries. 
The thumbnail, which is built into the wall of the house, is too small to see, so I´ve put it in as an extra.  It may have ben removed from the convent; it´s known as the Estela de Oculatio and is listed as Roman. The listing, which I don´t understand, is  CIL 2.5741
