In the summer of 1960, three priests were fishing on the shores of Lough Ree when they spotted a creature, six feet long, with its head and neck above the water's surface.
So began the legend of the Lough Ree Monster - maybe not quite a rival to the Lough Ness Monster but nonetheless a boon to the fortunes of tourism promoters in Westmeath, Longford and Roscommon.
Not that Lough Ree needs gimmicks to attract visitors. It's popular enough already among anglers, birdwatchers, and people who just like messing about in boats.
About a kilometre from the lake on its eastern shore is a restored 19th-century cottage in the townland of Creggan, near Glasson.
And only 150 metres from the house is the lesser lake known as Cleggan Lough - a pretty spot in itself even though it has no claims to a monster of its own.
A house is marked on this site on the first-edition Ordnance Survey map, when the entire townland was occupied by smallholders. The place has grown substantially since its early days though, now standing at 2,288 sq ft, but there are period features aplenty within.
The most conspicuous of these features are the beamed ceilings throughout. There's also a big inglenook fireplace in the living room, fitted with a range, and a brick fireplace in the sitting room, where there's a wood-burning stove.
The living room has an archway leading through to the eat-in kitchen, and there's a separate utility area along with four bedrooms (one with an en suite).
The attic consists of an L-shaped storage area.
The cottage is on three-quarters of an acre and is about 15 kilometres from the picturesque village of Glasson and an hour-and-a-half by car from Dublin.
It's for sale with Sherry FitzGerald O'Meara (0906) 475 500 for €239,000.
