Here also stands a chambered cromlech of four huge flat blocks roofed over like the cromlech under Slieve Callan across the Shannon mouth.

We have said much of the archaic cromlechs.

Just beyond the young stream of the Shannon, where it links Lough Garra to Lough Key, there is a lonely cromlech, whose tremendous crown was once upheld by five massive pillars.

At Drumbo, on the east bank of the Lagan before it reaches Belfast Lough, there is a massive cromlech surrounded by a wide ring of earth piled up high enough to cut off the sacred space within from all view of the outer world.

Under the shoulder of the great hill, with the rolling moorlands all about it, stands a solitary cromlech; formed of huge flat stones, it was at first a roomy chamber shut in on all four sides, and roofed by a single enormous block; the ends have fallen, so that it is now an open tunnel formed of three huge stones.

It might have been a titanic cromlech planted there in mid-ocean by hands accustomed to proportion their labours to the great deep.
