# Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales

The Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales is a heritage register of significant historic parks and gardens in Wales. It is maintained by Cadw, the historic environment service of the Welsh Government and was given statutory status in 2022.

## The Register

In 1992, when Elisabeth Whittle described Cadw as having a "somewhat special and guiding role" in the preservation of historic parks and gardens, since they are "an integral part of Welsh archaeological and architectural heritage", a collaboration between Cadw and the International Council on Monuments and Sites (ICOMOS) was working to compile the Register of Landscapes, Parks, and Gardens of Special Historic Interest in Wales. Part 1 of this, the Register of Parks and Gardens of Special Historic Interest in Wales, was published in six volumes between 1994 and 2002, each covering a particular area of Wales, and with an additional volume published in 2007.
The register of parks and gardens was given statutory status in 2022 and is administered by Cadw, the historic environment agency of the Welsh Government. The register includes just under 400 sites, ranging from gardens of private houses, to cemeteries and public parks. Parks and gardens are listed at one of three grades, matching the grading system used for listed buildings. Grade I is the highest grade, for sites of exceptional interest; Grade II*, the next highest, denotes parks and gardens of great quality; and Grade II denotes sites of special interest.
