Abbey Ruins.

These very attractive stone colours are at Kilwinning Abbey and monastery in North Ayrshire, Scotland.
It is I understand a type of limestone from a local quarry, (Goldcraigs freestone quarry)

Founded in the late 1100s it was the home of Tironensian Benedictine monks, who lived here for around 400 years, the majority of monks would have come from the Mother House of Kelso Abbey.
