O Castelo de Coina-A-Velha Notas a Propósito de Duas Plantas Antigas

Taking as a pretext the publication of two graphic documents concerning the forgotten Hisn of Coina-a-Velha (S. Lourenço de Azeitão), the authors synthesize the available information about this medieval fortifi cation, in its Islamic and Christian course. Although the testimonies of occupation are more remote, the architectural structure reveals a castle built by Muslim forces, around the 9th or 10th century, which survived after being incorporated into the space of the Christian kingdom. The last military events occurred in 1184 and 1191, both with harsh consequences on the fortifi cation, which must have been defi nitively abandoned in the early 13th century.
