Caernarfon Castle (Welsh: Castell Caernarfon) was constructed at Caernarfon in North Wales by King Edward I of England, following his conquest of the country in 1283. Edward I built castles and walled towns in North Wales to control the area following his conquest of the independent principality of Wales, in 1283. Llywelyn ap Gruffudd, prince of Wales, having rejected a bribe of one thousand pounds a year and an estate in England, if he would surrender his nation unreservedly to the king of England, had been lured into a trap on 11 December 1282, and put to death. His brother Dafydd ap Gruffudd had continued the struggle for continuing independence, but had been captured at Bera Mountain in the uplands above Garth Celyn, in June 1283. Edward surrounded and overshadowed Garth Celyn, the royal home and the headquarters of resistance to English domination, with Caernarfon and Conwy castles, and later Beaumaris Castle. The other fortress in the iron ring encirling Snowdonia was Harlech Castle. Edward II of England was born here, during the initial stages of the castle's construction in 1284.
