Caernarfon Castle

Caernarfon Castle is a medieval stone fortress occupying a prominent position in the town of Caernarfon on the eastern shore of the Menai Strait. The site hosted an earlier motte-and-bailey castle from the late 11th century and the present stone fortifications were begun under King Edward I in 1283 as part of his programme of conquest and administration in north Wales. The castle and the adjacent Edwardian town were conceived as a seat of English authority; the architecture intentionally referenced Roman and imperial models (linked in sources to the nearby Roman fort Segontium and compared to the Walls of Constantinople). Over the 19th and 20th centuries the castle has been a major tourist attraction and visual icon of Wales, documented extensively in postcards and prints (historical spellings such as "Carnarvon" appear in archival material). Historic and travel sources treat the site as one of Edward I's finest Welsh castles and as part of a World Heritage Site. Reported paranormal phenomena: the supplied research notes and sources contain no claims of apparitions, hauntings, named spirits, or other supernatural events associated with Caernarfon Castle. Accordingly, no specific paranormal events or entities are documented in this dataset. Interpretations and explanations in the sources are historical and architectural rather than supernatural. The castle remains open to visitors and features in contemporary tourism and heritage literature. Some non-scholarly sources present variant local historical claims (for example differing statements about early builders or precise founding dates) which are noted in archival and popular materials but do not include paranormal assertions.
