Cadw is the Welsh Government’s historic environment service. We work to protect and to celebrate the historic buildings, ancient monuments, historic landscapes and marine heritage of Wales for the benefit of people today and in the future.

We do this by:

  • Conserving, protecting and sustaining the historic environment.
  • Providing access to and promoting appreciation and enjoyment of the historic environment.
  • Working with partners, including specialists and experts, communities and local authorities to ensure the historic environment continues to contribute to the social, economic and environmental well-being of people in Wales.

Cadw is part of the Welsh Government’s Economy, Science and Transport Department and is answerable to the Deputy Minister for Culture, Sport and Tourism, Ken Skates AM.

Cadw is a Welsh word meaning ‘to keep’ or ‘to protect’.

Conserving, protecting and sustaining the historic environment

Cadw works to protect the historic environment for the benefit of current users, for the public at large and for future generations. 

We do this by:

  • Identifying places of special historic significance; this can affect permission for alterations or proposed works.
  • Providing advice to planning authorities as part of the statutory planning process and to other public bodies on environmental assessments. We also provide advice and guidance on good conservation practice to property owners and occupiers.

Cadw sites

Cadw manages 127 monuments on behalf of the Welsh Government. By providing access to these sites and using them as ‘showcases’ for the history of Wales, we aim to encourage people to explore and appreciate the historic environment. Traces of history are all around us and you are never far from a building or site of historic interest.

The historic environment of Wales

The sites managed by Cadw are a fraction of the historic sites, ancient monuments and historic features in Wales. There are traces of human activity in every part of Wales. Cadw and its partners are responsible for recording these traces and also for monitoring their condition.


To protect and promote the historic environment, Cadw works with a range of partner organizations and networks. These range from large national institutions to more modest local community groups — everyone has a part to play in the heritage of Wales.
