Rhos-on-Sea (Welsh: Llandrillo-yn-Rhos), also known as Rhos or Llandrillo, is a seaside resort and community in Conwy County Borough, Wales. The population was 7,110 in 2001, increasing to 7,593 at the 2011 census. It adjoins Colwyn Bay. It is named after the Welsh kingdom of Rhos established there in late Roman times as a sub-kingdom of Gwynedd, and later became a cantref (hundred).
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 graveyard here contains the grave of Harold Lowe, an officer on the RMS Titanic. He was widely regarded as a hero, helping many to safety with cool nerve and bravery. It also contains war graves of eight service personnel, two of World War I and six of World War II.
In 1186 Llywelyn the Great permitted the establishment of the Cistercian Aberconwy Abbey, and the monks built a fishing weir on the sea shore below Bryn Euryn. The place became known as Rhos Fynach, heath of the monks. In a charter of 1230, Llywelyn sanctioned the purchase by Ednyfed Fychan of land at Rhos Fynach and in 1289, the abbey moved to Maenan (becoming Maenan Abbey), and the weir was ceded to Ednyfed's estate. Eventually Rhos Fynach and the weir came into the hands of Robert Dudley, Earl of Leicester, who in 1575 granted it to a Captain Morgan ap John ap David, a privateer, for services rendered against the enemies of Queen Elizabeth I at sea. (This is not the famous pirate of the Caribbean Captain Henry Morgan who lived in the century following).
The weir continued to provide a prosperous livelihood through to the early 20th century: during a single night in 1850, 35,000 herring were caught, and 10 tons of mackerel were removed in one tide as late as 1907. Because such weirs decimated inshore fish stocks, Parliament banned them in 1861 unless it could be shown they pre-dated the Magna Carta, which the then owners, the Parry Evans family, were able to prove. Their estate included Rhos Fynach house, also known as Rhos Farm, on the Promenade near St Trillo's Chapel. The house is now a pub and restaurant. Its date of construction is not known for sure, but it is considered to have been started by the Cistercians before the Dissolution of the Monasteries.
St Trillo's Chapel
The chapel by the sea is on the site of a pre-Christian, sacred holy well; the altar is built directly over the pure water of the well. Saint Trillo, the son of Ithel Hael from Llydaw (Snowdonia) also founded a church at Llandrillo in Denbighshire. Trillo's brother Tygai (Llandygai) founded a church near Penrhyn, Bangor; their sister Llechid founded a church (Llanllechid) in the uplands above Penrhyn.
- Rhos-on-Sea also has the first permanent puppet theatre to be built in Britain, the Harlequin Puppet Theatre, which opened on 7 July 1958, when it won the Civic Trust Award for its design. Founders Eric Bramall and Chris Somerville have also created many puppet programmes for BBC children's television over a forty-year period. Many of the puppets created for these television series are now on display at the National Trust Property "Penrhyn Castle".

- The Society of St. Pius X operates its only chapel for Welsh Traditionalist Catholics in Rhos-on-Sea. The chapel is located in a renovated Methodist church on Conwy Road.
Rhos-on-Sea is also divided into two community wards, of Rhos and Dinarth. Rhos elects up to five councillors and Dinarth elects up to three councillors to the Bay of Colwyn Town Council (which was formed in 1996).
- David Jones and Rhos - The poet and visual artist David Jones visited Rhos-on-Sea in 1904 when he was 9. It was his first ever trip to Wales and it made an enormous impression on him. His father's family lived in Rhos, and the young Jones played with his cousins at St. Trillo's Chapel, and on Bryn Euryn. He also particularly loved the fishing weir just a few yards from St. Trillos. These were formative influences both on his writing and visual art. He wrote that this visit left 'an indelible mark on my soul'.
- In 1937, after the death of his mother, Jones revisited Rhos. He found it a 'wilderness of villas and bungalows'. The fishing weir had gone (there remain a few stumps), and the chapel was now 'cleared and cared for', but it had 'lost half its numinous feeling'.
- Madog and claims for the discovery of America - According to legend, Madog ap Owain Gwynedd, a Welsh prince of Gwynedd, sailed from here in 1170 and discovered America, over three hundred years before Christopher Columbus's famous voyage in 1492. This event is recorded by a plaque on one of the properties on the sea-front.
- This property is called "Odstone" at no. 179, Marine Drive which, as of June 2012, has become neglected. As of Sept 2017, this house has been demolished.
