A small market town on the north coast between Colwyn Bay and Rhyl, Abergele has a population of around 10,500. This includes its northern suburb on Pensarn which has a long sweeping shingle and pebble beach. Abergele was the site of an important clas (Celtic monastery) and remained settled into the thirteenth century. Edward I is known to have briefly stayed there in December 1294 during his invasion of Wales to suppress the revolt of Madog ap Llywelyn.
Sites of historical interest include two Iron Age hillforts; Castell Cawr at Tan y Gopa and Pen y Corddyn Mawr hill above Rhyd y Foel. On Gallt y Felin Wynt, a hill above the town, is a C17th watchtower; the Lady Emilys Tower is located near Cefn yr Ogof. Gwrych Castle was built between 1819 and 1825 for Lloyd Hesketh Bamford-Hesketh.
