Mizen Magic 13: Dunmanus Promontory

It’s geologically and archaeologically fascinating – a substantial natural promontory just to the north of Dunmanus Castle: well worth an exploration. But, do be warned – there are cliff edges, exposed fissures, ankle-wrenching undulations and bogs to overcome. Also – it’s private, so please seek permission before crossing the land.

The west side of this shark’s fin-shaped promontory is wildly exposed to the ocean and its gales. You can see from the aerial views, above, how the rock bed is bare and visible, and the vestigial fields which occupy – or once occupied – the east side peter out, and the walls and banks which once formed them fade away altogether over on the left. In fact, these Google Earth images give a better impression of the oddly shaped enclosures than can be seen on the ground.

Three examples of many varied boundary features on the promontory are shown above. Each is differently constructed and they range from a series of vertically-set slabs to rocks-and-rubble and a raised bank reinforced with stones. In the picture below, follow with your eye the boundary as it traverses the scrub and makes a large S-bend on to the ridge facing the distant horizon.

Ireland – especially the west of it – is a huge stone landscape. Wherever people have settled, they have moved the stone and used it. To make fields, or any enclosures, they have had to clear the land. The stone taken from the land is used – sometimes to build shelter, often to build myriad walls to define the holdings. Here’s a striking example from the Aran Islands:

Nothing is recorded on the National Monuments Survey about these land boundaries at Dunmanus – or the significance of the promontory as a whole. Was it once a promontory fort? There are others on this coast. It could easily have been defended along the line of the present road running across the south. However, the land is flat and low, and there is no shelter.

Flat stone surfaces – of old red sandstone – remind us of the Burren landscape in Clare, and we can suppose that the present windswept bog and scrub could once have supported agriculture. But when? In medieval times, perhaps, when the nearby Dunmanus tower house was a thriving centre of occupation and, probably, commerce. In the shelter of the bay the little quay at Dunmanus survives and is still used by small boats searching out shellfish and scallops.

In some places the old walls seem to have a prehistoric feel: the use of slabs embedded vertically like standing stones is quite unusual in West Cork. The presence of large quartz rocks, too, is reminiscent of ancient sites, although they are natural geological occurrences here.

Other natural features on the peninsula include two ‘sea arches’ – bridges formed through erosion of the rocks and chasms by the ocean.

It’s a landscape of vestigial fields, sea – and stones. Nothing more. But I find it a mesmeric place; partly because we can see that it bears the marks of human toil, and we want to know more about who was there and how they lived. It’s a remote piece of Ireland to call ‘home’. Those marks remain after how many years – hundreds, thousands? They intrigue us, and compel us to explore.
