For the purposes of the SCRCA Project, retaining walls are large masonry structures that stabilise and reinforce the sides of steep-sided cuttings and embankments. Retaining walls will only be included in the database if they match one or more of the following criteria:
- they are visible from a publicly accessible location,
- they are interesting (i.e. there is the potential for an associated article) and / or
- they are particularly impressive (in terms of their size and appearance).
