==History== Llanrwst takes its name from Saint Grwst, a 6th-century saint. The first church dedicated to him at Llanrwst was on a site now occupied by Seion Methodist Chapel, between Station Road and Cae Llan. A second church of St Grwst was built on a new site a short distance south of its predecessor, on the banks of the Conwy. The site was donated for the purpose in about 1170 by Rhun ap Nefydd Hardd, a member of the royal family of Gwynedd. The second church was replaced by the current building on the same site in the late 15th century.
