Castles, scattered across our landscape are probably the most noticeable part of our heritage. From the large medieval castles to the lesser known, Welsh castles, each having a story to tell. Many of our earlier castles have disappeared, leaving just a few traces as testament to their existence where they once stood. They were either destroyed or used as building materials for the early churches and later medieval castles.
Most castles were constructed from wood and therefore not built to last. Some were adapted on previous defensive strongholds such as hillforts, leaving traces of defensive walls and mounds of earthwork and the occasional remains of a motte & bailey. This is mostly the case with the Norman castles built between 1088 and 1115 during the Norman Conquest.
Although Llywelyn the Great constructed some magnificent medieval strongholds, only Dolbadarn and Dolwyddelan are now standing. However, the most impressive of all are the large medieval castles, which were constructed by King Edward I of England to subdue the Welsh after the death of our last prince Llywelyn ap Gruffydd in 1282. Today we appreciate these large castles such as Caernarfon, Conwy, Beaumaris & Harlech – as they bring visitors from around the world.
