Round Tower of Kilmacduagh, north of Limerick in county Galway, is the tallest of the Irish towers at 34 meters and, while quite stable, appears to be tilting precariously. Little is known of the adjoining monastery, probably founded in the early 7th century, and it is assumed that the round tower was erected sometime in the 10th or 11th centuries. Around 65 round towers are known in various states of decay throughout Ireland. However their origin and purpose is debated. Hypotheses include that they were used as bell towers, or as protection against raids.
Kilmacduagh’s round tower excels in terms of its condition, location and height.
