Construction utilizes local Old Red Sandstone, dry-laid to withstand coastal weather conditions.
The interior clochán remains are a rare example of domestic architecture still visible within a defensive cashel.
The site was subject to extensive conservation and excavation work by the Office of Public Works in the early 2000s.
Evidence of iron forging at the site indicates the residents possessed advanced metalworking technology for the period.
The wall features an internal staircase, which provided defenders access to the rampart's top.
It is located less than 500 meters from the larger Leacanabuaile Stone Fort.
Cahergal Stone Fort is a well-preserved Early Medieval cashel situated on the Iveragh Peninsula in County Kerry. The dry-stone enclosure features a circular rampart built without mortar, measuring approximately 25 meters in internal diameter. The walls reach up to 4 meters in height and are 3.5 to 5 meters thick at the base. Internally, the fort contains the remains of a dry-stone corbelled beehive hut, or clochán, near the eastern wall. Excavations have revealed evidence of domestic occupation, including hearths and iron-working remains. The structure is accessed via a single entrance passage located on the southeast side. It sits on a rocky outcrop overlooking the Atlantic coastline. Archaeological estimates suggest the fort dates to the 7th century AD.

Wear waterproof footwear as the ground surrounding the fort can be uneven and boggy.
Combine your visit with the neighboring Leacanabuaile Stone Fort to contrast the two structures.
Exercise caution on the interior wall stairs as they are steep and lack railings.
Do not attempt to park directly on the narrow access road; use the designated pull-offs.
Do not climb or remove stones from the dry-stone walls as they are fragile historical artifacts.
