Dysart Castle

Dysart Castle is a medieval fortress beside the River Nore near Thomastown, featuring substantial stone walls with large windows visible on its upper levels. A church stands immediately adjacent to the structure, forming part of the same site.

The castle dates to the 14th century and was connected to Kells Priory monastery until 1540. It passed to the Butler family when the monasteries were dissolved during that period.

The site is connected to the Berkeley family, who made their home here and produced the philosopher George Berkeley. His name remains linked to institutions in California and Trinity College Dublin.

The structure is in poor condition and requires careful attention when visiting. The location offers good views of the surrounding landscape and the nearby river, making it part of a pleasant walk through the area.

The site originally held little economic value but increased significantly in worth over a century. This rise in value shows how the property became more important to the region over time.
