Llanrhos Church is located two miles South of Llandudno and two miles East of Deganwy in a beautiful country setting. The church is dedicated to St. Hilary and is in the diocese of Saint Asaph. It is the oldest church in the parish of Llanrhos yet the church we see today was extensively rebuilt in 1865.

But the practice of Christianity here goes way back to the mid 6th Century as Maelgwn King of Gwynedd  (who occupied a stronghold on the hills called the Vardre above Deganwy) built the original church on this site. Indeed Maelgwn (Maelgwyn) himself sought sanctuary in the church from the great yellow fever that was spreading throughout the country. He prostrated himself before the altar of the church and prayed for his life, but it was to no avail and he died a few days later.

The original church was replaced in about 1282, (one of the church's Fonts dates from the Norman period) and although this medieval church was yet again replaced in the 19th Century it is believed that the Nave and Chancel walls were built by monks from the monastery at Maenan Abbey in the Conwy valley and that the present building incorporates the roof beams and several other features of the late medieval church.

The church is in a charming location, it is popular for wedding ceremonies, and the grave yard looks a nice place to rest. Behind the church is Llanrhos schoolroom. This was founded in 1822 to educate boys and girls from poor families in the parish and today it is used as the Church Hall and Sunday school. Close by is Ffynnon Santes Fair (Saint Mary's Well) . A local resident Mr Ken Davies of Llanrhos tells the story of how he rediscovered the old well in January 1994 and the work that took place to clear the site and expose the well.

Llanrhos Church is just a few miles away from what is probably the smallest church in Britain. St Trillo's Chapel and Holy Well is on the sea front nearby at Rhos on Sea.
