The Motte
Although the Norman invasion of Ireland took place in 1169, Clonard was not occupied by them until some time after 1177 when the Norman Lord, Hugh De Lacy directed the military occupation of much of this western area of Meath, Mottes were erected on principal roads and in important ecclesiastical centres such as Clonard, which then became a garrison town. 
This high motte was erected east of the Clonard river, surrounded by the usual Norman fortifications and flanked by the usual bailey. Its perpendicular height is 50 feet and its lower circumference measures 432 feet, the top which is flat is crowned by an impressive stately lime tree. This 12th century Norman motte has become a well known landmark in the area.
