Arklow was founded by the Vikings in the ninth century and was the location of one of the bloodiest battles of the 1798 rebellion. Arklow is now a thriving commuter town with a population of around 16,000.
It is the second largest town in Co. Wicklow. Arklow is situated at the mouth of the River Avoca, the longest river entirely within County Wicklow.
The town is divided by the river, which is crossed by the Nineteen Arches Bridge, a stone arch bridge linking the south or main part of the town with the north part, called Ferrybank.
