Long Meg and Her Daughters is a Neolithic stone circle situated north-east of Penrith near Little Salkeld in Cumbria, North West England.

One of around 1,300 stone circles in the British Isles and Brittany, it was constructed as a part of a megalithic tradition that emerged during Neolithic, and continued into the Early Bronze Age (circa 3200 - 2500BC).

It consists of 66 stones[2] (of which 27 remain upright) set in an east / west oval configuration measuring 380 ft (120 m) on its long axis.

[9] The Long Meg monolith and accompanying circle (grid reference NY571372) forms one part of a complex of monuments in the Penrith area that includes, as well as the nearby Little Meg circle, a smaller circle seen by William Stukeley in 1725 to the south-west, no longer extant, plus the impressive Mayburgh Henge at Eamont Bridge, a partly destroyed henge at nearby King Arthur's Round Table, and a third, completely destroyed, henge just a few yards to the south of King Arthur's Round Table.

These incliude: Little Meg, Glassonby Stone Circle, and the lost Old Parks Cairn, all of which are decorated with rock art.

[11] Long Meg and her Daughters lie on a terrace above water, immediately to the south of a ditched enclosure that runs round the present farm.

Although the circle appears to have been built on a slope, Clare suggests that the large enclosure was made across a valley up to 16 ft (4.9 m) deep.

"[14] The Long Meg monolith is of local red sandstone, probably from the River Eden or the nearby Lazonby hills, whereas the circle stones are of rhyolite and are glacial erratics.

[15] The English antiquary William Dugdale (1605–1686) reported that there were "two barrows of cobble-stones, nine or ten feet high" in the centre of the circle.

They seem to have been deliberately selected and placed at specific points in the circle that mark certain calendrical events (sunsets and solstices related to the four seasons, for example).

In this respect, it may be of the same date as other enclosures found in Cumbria that include: Carrock Fell, Skelmore Heads, Howe Robin, and Green How.

Clare summarises the various arguments concerning types, purpose, construction, size, layout, origins and dates, of Cumbrian stone circles and other monuments.

Another legend states that if you walk round the circles and count the number of stones correctly, then put your ear to Long Meg, you will hear her whisper.
