Llys Rhosyr

Llys Rhosyr is the site of a medieval royal administrative center with stone foundations still visible across the landscape. The layout shows where halls, kitchens, and living quarters once stood within the larger complex.

This site served as an administrative center for Welsh princes until Edward I conquered north Wales in 1282. English rule ended its former role and the site gradually lost its political importance.

The site reveals how people lived and worked within a medieval princely court through scattered household items and tools. Daily routines of both high-status residents and servants become visible through the objects found in the excavations.

The site is open ground that can be visited without special arrangements. A nearby institute displays artifacts and provides information about the medieval Welsh court system to help understand what stood here.

A severe sandstorm in winter 1332 buried much of the site and naturally preserved the remains for centuries. This accidental protection allowed archaeologists to later uncover the complex with remarkable clarity.
