Moated site, Thomastown Demesne South, Co. Tipperary South
This particular rectangular enclosure, measuring 32 metres north to south and 28 metres east to west, forms part of a larger defensive network, with another moated site directly adjoining it to the east and a third to the south. The site is defined by earthen banks on its eastern and northern sides, with the northern bank stretching 29 metres long and standing over 1.5 metres high on its outer face, whilst the southern and western boundaries are marked by scarps about a metre in height.
The defensive features of this site reveal sophisticated medieval engineering. A shallow external fosse, or defensive ditch, runs along the northern side at roughly 5.6 metres wide, whilst the eastern side shares a much more substantial fosse with its neighbouring moated site; this shared ditch measures 7 metres wide and 1.2 metres deep. Traces of an additional narrow outer bank and a second external fosse can still be detected on the northern side, suggesting multiple phases of fortification. The interior of the monument slopes gently downwards towards the south-southeast, and at its centre lie the remains of what appear to be conjoined hut sites or internal structures.
Beyond its defensive earthworks, the site preserves evidence of a complex water management system. A slightly sinuous leat, or artificial water channel, extends west-southwest from the external fosse, likely serving as the outflow channel for the entire complex as it follows the natural downslope of the land. This water feature, along with the surrounding field systems visible to the south and southeast, paints a picture of a well-planned medieval settlement that balanced defensive needs with practical considerations of drainage and agriculture. The interconnected nature of these three moated sites suggests they may have functioned as a single administrative or defensive unit during the medieval period.
