In the demesne, the lands around the House and temple, are various places of interest.
The Bishop’s Gate with its Gothic gate lodge with symbolic carvings such as the bishop’s mitre and cow skulls.
An empty tomb or mausoleum, dovecote and ice house can also be found along the mown grass pathways. The Black Glen, the Bog Garden and Walled Garden are full of trees, flowers and peaceful, sheltered places to walk. From there a path running alongside and above the ocean, leads down into Castlerock .
