Domen Ddreiniog, Llanegryn

Also known as, or recorded in historical documents as; Tomen Ddreiniog; Thorny Motte; Tal y Bont

In the community of Llanegryn.
In the historic county of Merioneth (Modern authority of Gwynedd, preserved county of Gwynedd).

Overgrown hillock on the very edge of the Dysynni. Its history can be inferred only from what is known of similar constructions elsewhere. It has been linked with Castell Cynfael and Tomen Las near Pennal as one of the Motte and Bailey Castles built by the Normans during the phase of expansion, and destroyed, or taken over by the Welsh towards the end of C11. The very marked meander of the river north-east of the motte provides an ideally defended site but presumably, even if the loop was there in mediaeval times, the land inside it was too wet and subject to violent floods to be suitable.

This site has been described as a;
Timber Castle.
The confidence that this site is a medieval fortification or palace is Certain.
Earthworks remains.

This site is a scheduled monument protected by law.
