At the top of the rockworks are two large lumps of clinker, each at the head of ‘steps’ down which a trickle of water could flow.
Clinker from the gasworks was used by Henry Trevor as a cheap substitute for the volcanic rock which was advised as desirable for Victorian rockworks.
Marj Wilson designed a planting for the elevation which included ferns and cordyline. In the background can be seen one of the copper beeches which Henry Trevor planted.
