A protected structure is a structure that a planning authority considers to be of special interest from an

• architectural,
• historical,
• archaeological,
• artistic,
• cultural,
• scientific,
• social, or
• technical point of view.

Every planning authority must have a Record of Protected Structures (RPS) that includes all structures of special interest in its area and into which details of protected structures are entered. The RPS forms part of the Development Plan.

Each owner and occupier of a Protected Structure must ensure that a protected structure, nor any element of a protected structure that contributes to its special interest, is not endangered through harm, decay or damage, whether over a short or long period, through neglect, through direct or indirect means. This duty is the same for owners and occupiers of proposed protected structures. In general, if a structure is maintained in a habitable condition and routine maintenance carried out (e.g. cleaning out gutters, repair of slipped slates), then it should not become endangered.

The protection applies to all parts of the structure that contribute to its character and special interest, including its interior, surrounding land or 'curtilage', and any other structures on that land, and their interiors, and all fixtures and features of these structures.
