Description:
The ancient architecture that is most specific to Ireland is the round tower. In no other part of the world does one find a similar construction. Round towers were first mentioned c.950, when a round tower burned down. They were on average between 60ft and 130ft high and the main door was located 7-13ft above ground level. Round towers were not built for a single purpose.
