Abbey River, Limerick 1.96

The Abbey River is a distributary arm of the River Shannon that flows around the northeastern, eastern, and southern shores of King's Island, Limerick before rejoining the Shannon at Hellsgate Island. Hellsgate Island is only visible at low tide. It is bridged by the Abbey Bridge, Baals Bridge, the Canal Bridge, Matthew Bridge, O'Dwyer Bridge, and the Sylvester O'Halloran Footbridge.King's Island's encirclement by the Shannon and Abbey rivers made it a very defensible location, leading to the founding of Limerick as a Viking settlement in the ninth century. The Abbey River has played a defensive role throughout the city's history, not least during the Cromwellian siege of 1650-51, and the Williamite siege of 1691.
