The Great Orme is a limestone headland that is about 2 miles long, 1 mile wide and 679 ft high and is adjacent to the seaside resort of Llandudno.
It has been extensively mined since prehistoric times for a range of resources including copper. There are a large number of mines in the area of varying sizes.
Great Orme mine was discovered in 1987 during a landscaping project and has been dated to about 4000 years ago. It continues to be explored and researched.
It is open to the public March - October and visitors have a 45 minute self-guided tour of a 200m underground section as well as a surface exhibition, opencast mine and smelting area.
