Carnarfom Castle was built by King Edward the 1st of England after he had conquered Wales in 1277,
building started on the castle in 1323 and cost a massive £22,000, but it never ever got finished.
Here is an aerial photo of the castle to give you a better idea of just how big it is!!!
It was built on the mouth of the River Seiont that flows into Caernarfon Bay.

In 1911 the future Edward v111 was invested at the castle, as was Prince Charles, in 1969, which made him The Prince of Wales.
