Prehistoric Killarney
Killarney's unique history began with the last Ice Age. A single ice sheet covered the entire region. As it melted, it sculpted Killarney's magnificent peaks Carrantoohill, Crohane, Tomies, Torc, and Mangerton. Pushing aside huge boulders and gravel, it created the winding passes of Moll's Gap and the Gap of Dunloe. The retreating ice also formed dark, mysterious loughs. The Long Range (Upper Lake, Muckross Lake, and Lough Leane), Lough Guitane, and the Devil's Punch Bowl are all glacial remnants.
Erosion over long periods has continued to form other beauty spots. The Upper Lake, Muckross Lake, and Lough Leane briefly combine at the Meeting of the Waters, creating a mass of small ripples before parting again. Water draining from the Devil's Punch Bowl is responsible for the spectacular Torc Waterfall, while mountain streams join and tumble down at O'Sullivan's Cascade.
The area's first human residents were Bronze Age Beaker Folk, from around 2000 BC. They mined copper on Ross Island and also left the open-air temple at Lissyvigeen. Beginning in 500 BC, successive waves of invaders culturally changed the area. Pictish tribes from the north of Ireland were the first invaders. According to legend, the ruling tribe in Killarney was descended from Queen Mebh's son Cair and was known as the Ciarraige. It is from this name that "Kerry" is derived.
In approximately 400 BC, the next wave came with the Fir Bolg or Iverni. The name Fir Bolg means, "bag men." One explanation often given for this name is that they exported Irish earth to the Greeks to protect their cities from snakes. Expert stonemasons, the Fir Bolg created the stone forts Staigue, Cahergall, and Leacanabuaile centuries later. They also developed Ogham script, fine examples of which can be found near Killarney. A Celtic people, they gave Ireland some of its richest legends. The tales of Cuchulainn, Deirdre, and Curoi are all attributed to them; it is thought that the great Irish saga 'Tain' tells of the Fir Bolg's battles with the next invasion group, the Gaels.
The Gaels - who later called themselves the Milesians - arrived in 100 BC. Although a fierce, warring race, it still took them 500 years to dominate the other two groups and eventually settle their power base around Killarney.
The Arrival of Christianity
Until 400 AD, Killarney remained under Gael rule with the Ciarraige and Fir Bolg paying tributes. The first Christian communities were established around this time with St. Abban building a cell at Aghadoe. Christianity was accepted quite readily in Kerry, with pagan festivals and rites readily assimilated. By 633 AD, Gael, Faithliu, established the monestary on Innishfallen Island. Although the Geraldines came as far as Aghadoe and built a castle on the site of Parkavonear, the Gaels ruled undisturbed for 200 years until they were overthrown by the O'Donoghue/MacCarthy's. From 1200 onwards, the Anglo-Normans, based at Ballymalis Castle, launched successive attacks on the O'Donoghue/MacCarthy chieftains and were defeated in 1261. During the relatively peaceful centuries that followed, the O'Donoghue/MacCarthy family built Ross Castle and Muckross Abbey. Then in 1583, the English defeated the O'Donoghue/MacCarthy's, and most of their lands were awarded to Sir Vincent Browne.
