Garden Walls N of Bryn Iorcyn Manor including range of pigsties W of the house

The garden walls north of Bryn Iorcyn Manor, along with a range of pigsties to the west of the house, are constructed of stone rubble. Some sections feature a roughly shaped stone parapet, while others have a flat parapet. A short section of the wall that once divided the garden remains as a stub extending north from the northeast corner of the house. The eastern wall includes a circular hole that has been repaired with a brick relieving arch, providing a view of Caergwrle Castle.

On the inner face of the western return wall, directly facing the house, there is a range of two pairs of pigsties topped with a continuous slate roof. The runs for the pigs are stone paved and separated by a stone wall with stone gatepiers. The northernmost pair of pigsties has a loft, likely used for poultry, accessed through a gabled dormer that rises from the eaves. To the north of the pigsties, an entrance in the wall leads to a track that runs west of the gardens. The southern wall connects the pigsties to the southwest tip of the western wing of the house. The interior of the pigsties was not inspected during the 1997 survey.
