The Little Orme was inhabited during the
Mesolithic and
Neolithic eras, notably the
Pant y Wennol cave. A small hoard of
Iron Age Celtic metalwork was found in a cave on the Little Orme. The medieval chapel of Blessed Mary of Penrhyn, abandoned in 1930 and now in ruins, is at the foot of the Little Orme in the grounds of Penrhyn Hall at Penrhyn Bay. On 14 April 1587, printing material for
Catholic literature was found in a cave on the Little Orme, where it had been used by the recusant Robert Pugh (squire of Penrhyn Hall) and his Chaplain Father William Davies to print
Y Drych Cristianogawl (
The Christian Mirror), the first book to be printed in Wales. They had taken refuge there during the persecution of Catholics instigated by
Queen Elizabeth I in May 1586. The
Royal Artillery coastal gunnery school, 198 battery, was posted to Little Orme during the
Second World War. Target practice was undertaken from the headland to anchored boats, and unspent ammunition and unexploded shells may still be encountered offshore. Gun emplacements and ancillary buildings were in situ until at least the early 1960s, but the site has since been landscaped. ==Ecology and environment==
