We don't have to go back far in time to find an emblematic convent: Celanova, with the peculiarity of a tiny, pre-Romanesque church dedicated to San Miguel in its complex. Santa Comba de Bande is pre-Romanesque, as well.
For its part, A Limia's esplanade is defended by four towers. Three of them are sure to impress anyone. These are: Sandiás (an example of how to challenge heights), A Pena (in Xinzo, dominating the northernmost part and in very good condition) and A Forxa (in the municipality of Porqueira), and one more, of which remain only the ruins on top of a mountain, which allows it to look out over the entire plain (Celma, in Rairiz de Veiga). There are at least three more fortifications that must be mentioned: Araúxo castle in Lobios – only ruins remain, but on a site that commands a spectacular view –, Vilanova Tower, in Celanova, which ended up housing the offices of the town council, and the inaccessible Sande Castle (also in Celanova).
