In the Dublin Museum can be seen the bookshrine known as the Cumdach of St. Molaise. It is dated as early as the eleventh century. Alas the manuscript is missing.

Further up the gentle slope is the most beautiful Round Tower in Ireland. It was an early tenth-century bell tower and place of refuge from the Vikings who raided all Lough Erne's monasteries for over two hundred years.

It is eighty one feet high with beautifully cut and shaped masonry. The round arched entrance is nearly nine feet above ground level and the tower originally had five floors. Ropes or ladders were used to gain access to each level.

The diameter of the tower at the base is only eighteen feet but the walls themselves are over four feet thick. Below the conical stone roof near the top is a cornice of Celtic design in which are set four heads of Celtic Saints. These tall slender towers are seldom found outside Ireland but on Iona the remains of one can still be seen.
