 In the 21st century, four exemplifications of the original 1215 charter remain in existence, two at the British Library, one at Lincoln Castle and one at Salisbury Cathedral.There are also a handful of the subsequent charters in public and private ownership, including copies of the 1297 charter in both the United States and Australia.The original charters were written on parchment sheets using quill pens, in heavily abbreviated medieval Latin, which was the convention for legal documents at that time.
