The Cronaniv Burn (Irish: Abhainn Chró Nimhe, meaning 'Poisoned Glen River';[1][2][3] the English name of the burn probably comes from the version Cró na Nimhe, meaning 'Hollow / Glen of the Poison'[2]) is a burn or small river that flows through the Poisoned Glen in Gaoth Dobhair, a district in the north-west of County Donegal in Ulster, the northern province in Ireland.

[1][2][3][4] In the Ulster Scots dialect, a 'burn' is a stream or small river.

The Devlin River then flows on for a few hundred yards, flowing into Dunlewey Lough (Irish: Loch Dhún Lúiche), the river emptying into the south-eastern end of the lough.

This former church, located on the southern outskirts of Dunlewey, was built in the neo-Gothic style in the early 1850s.

[6][7][8][9] The building was formerly a 'chapel of ease' for the Church of Ireland Parish of Tullaghobegley.
