Victoria Lock, canal lock in Clonahenoge, County Offaly, Ireland

Victoria Lock is a waterway lock on the River Shannon between Meelick and Clonahenoge, serving as the first lock upstream from Lough Derg. Stone walls and heavy gates allow boats to move between different water levels as they travel along this section of the river.

Thomas Rhodes built Victoria Lock in the 1840s on the instructions of the Shannon Commissioners, as part of a widescale upgrade of the Shannon Navigation. It is the first lock on the river upstream of Lough Derg, standing where the Little Brosna River enters the Shannon between Meelick, County Galway and Clonahenoge, County Offaly. A second lock, Hamilton Lock, lies nearby and is now disused.

The lock is accessible by foot from nearby paths and offers good views across the Shannon. Visit during dry weather when the surrounding ground is firm and safe to walk on.

Cast-iron bollards from 1844 made by Fenton, Murray and Jackson Engineers of Leeds still stand at the lock. These rare original pieces show the industrial craftsmanship of the era when the lock was built.
