The Rock Garden was a more common garden feature in the past, it has now fallen into decline somewhat. Sometimes arranged to depict an ancient ruin or alpine scene the rockery could be a stunning feature with its own unique planting scheme. Many large houses in Ireland had rock gardens in Victorian times, most of which were lost to progress or even been used as building stone in some cases.
Planning and restoring an historic Rock Garden can be a specialised area when attempting to recreate an old planting scheme to be faithful to the original.
