Victoria Lock, also known as Meelick Lock, is situated between Meelick, Co. Galway and Clonahenoge, Co. Offaly and is the first lock on the River Shannon upstream from Lough Derg. It is near the tripoint where the provinces of Munster, Leinster and Connacht all meet.
Still in use today, this lock was first constructed by Thomas Rhodes on the instruction of the Shannon Commissioners in the 1840s as part of a widescale upgrade of the Shannon Navigation. It is this upgrade that also brings changes and improvements to the bridge at Banagher. The is also a second lock nearby, called Hamilton lock that is now disused.
