St Grwst's Church is a late-medieval parish church in Llanrwst, rebuilt in the 15th century on an older religious site. The Gwydir Chapel, added in the 1630s by the Wynn family of nearby Gwydir, gives the church much of its historical interest.
It is a quiet stop, but a good one if you are already following the Conwy Valley and visiting Gwydir Castle.
