The monastery at Monasterboice was founded by St Buite mac Bronaigh (d.521). In 1097 it is recorded that the cloig teach (round tower) of Monasterboice was burned with all its books and treasures. This is the only known direct evidence from the Annals for the storeroom function of the round tower. The cap appears to have fallen off the tower during the second half of the 18thc. Floors, ladders and a roof were installed in 1871 under the supervision of the Royal Society of Antiquaries of Ireland.
