Mourne Wall Centenary

This year, 2022, marks the one-hundredth anniversary of the completion of the Mourne Wall construction; a remarkable feat of craftmanship that has stood the test of time and harsh conditions over the century. Work on the wall began in 1904 and took 18-years to complete, providing a boundary for the 9,000-acre water catchment area that supplies the Silent Valley and Ben Crom reservoirs.

We are holding a number of special events and activities throughout 2022 and 2023 to celebrate this amazing feat.
