Great Pollet Sea Arch is one of Ireland's finest coastal geographical features. Situated off the coast of County Donegal's Fanad Peninsula, the sea arch stands at 20 metres above the crashing waves along this rocky headland.

Known in Irish as Stua Mór Phollaide (Great Pollet Arch), the sea arch as seen here separated from the mainland on the left due to coastal erosion during the millions of years since these rocks were formed.

Here the rocks are quartzite having been formed during the late Precambrian, somewhere between 2.5 billion and 541 million years ago part of the Dalradian Supergroup that runs between the north of Ireland and central Scotland.

As throughout Ireland, much erosion has taken place in the intervening time and at some point, likely in the last 11,700 years which is known as the Holocene (since the end of the last Ice Age) this section of the headland became a bridge with a sea cave eroded through it and then subsequently it became detached from the mainland behind it.

Thus forming what we see today, an impressive sea arch which is Ireland's largest sea arch. Note that a sea stack, such as Dun Briste is different to a sea arch.

I will be leading a few small group photography workshops in Donegal during 2024 and 2025, to find out more contact me using the contact page or form.

Photographing seascapes in Ireland is never boring. The varied geology of the Irish coast makes it interesting to say the least.

Here along the Wild Atlantic Way many rocks are evident, sedimentary layers are visible inclining out of the Atlantic while behind igneous rocks form the foreshore.

The rough sheep grazing land stretching uphill is dotted with rocks.

More seascapes can be found here with information on Panoramic Ireland's coastal photography workshops.

The Irish coastline is full of variation with long sandy beaches, rocky inlets and geological formations in a compact area.

And that makes Ireland a perfect place for coastal landscape photography.

Here the rocks are carboniferous limestone, in layers that have been long eroded by the wave action of the Atlantic.

We set up our cameras and tripods on the cold winter afternoon, hoping for some sunlight but actually in this case the overcast weather worked better.

I was at this point only a few weeks away from having an operation to remove a cancerous tumour, and during that time it was scenes like this that kept me motivated in my treatment and recovery.

I'm almost a year post-cancer; I'm still photographing, I'm still leading photography workshops and tours in Ireland and you can book a private photography session with me through the site here at Panoramic Ireland.

Send me an email to ask about photo workshops in your area of Ireland.
