Scheduled monuments in North Ayrshire

North Ayrshire shown within Scotland

A scheduled monument in Scotland is a nationally important archaeological site or monument which is given legal protection by being placed on a list (or "schedule") maintained by Historic Environment Scotland. The aim of scheduling is to preserve the country's most significant sites and monuments as far as possible in the form in which they have been inherited.

The process of scheduling is governed by the Ancient Monuments and Archaeological Areas Act 1979, which aims "to make provision for the investigation, preservation and recording of matters of archaeological or historical interest". The term "scheduled monument" can apply to the whole range of archaeological sites which have been deliberately constructed by human activity but are not always visible above ground. They range from prehistoric standing stones and burial sites, through Roman remains and medieval structures such as castles and monasteries, to later structures such as industrial sites and buildings constructed for the World Wars. Some buildings or structures which were both scheduled and listed have had their listing designations removed to reduce the duplication.

In 2017 there were 8,238 scheduled monuments in Scotland.
