The unfinished dam! No parking near by, so you might get lucky and be able to park on the road and walk down or you'll have to walk a distance from the nearest parking areas. There are two gates leading to the damn and it is pretty easy going. Very interesting to see a dam they never bothered finishing, to quote the Elan Valley website "Dol y Mynach is the unfinished dam. The original 1890s scheme for the sequence of dams and reservoirs in the Elan and Claerwen valleys included provision for three dams on the River Claerwen, which were intended to be constructed later when additional water supplies were needed for Birmingham. Caban Coch Dam was to create a reservoir with a top water level which would be above the level of the foundations of the dam at Dol y Mynach, the lowest of the planned three on the River Claerwen. It was therefore necessary to build the base of the Dol y Mynach Dam at the same time as the other dams in the adjacent valley of the River Elan. Huge blocks of stone, weighing anything up to ten tons set in concrete which form the solid core of the huge structure, can be seen between the outer faces of dressed masonry." I spotted it from the road originally and thought it was the one blown up for the Damn Busters, but google pointed out that was Nant y gro, which is a little bit further down from this.
