History
Bryn Euryn and Llys Euryn
Bryn Euryn is a hill overlooking Rhos-on-Sea on which there are the remains of a hillfort called Dinerth, the 'fort of the bear', and a limestone quarry. Ednyfed Fychan, 13th century seneschal to Llywelyn the Great and ancestor to the House of Tudor was granted the land and built a castle on the hill, of which all traces have disappeared, and a manor, Llys Euryn of which the ruins of its 15th-century reconstruction can be seen today.
Church of Llandrillo yn Rhos
Llandrillo yn Rhos Church was built on the site of Ednyfed Fychan's private chapel and incorporates what was his tombstone, the history of this church goes back to the 13th century, but having been rebuilt over the centuries, the oldest parts of the present church are 15th century. A major restoration was carried out in 1857 and was criticised by some for amounting to 'vandalism', in particular the destruction of an ancient stained glass window. Nevertheless, it remains one of the most important historic buildings in North Wales.
The stone lych-gate was built in 1677 and is one of the oldest in the district; the sundial is from the early 18th century.
