Geocache Description:

TO CLAIM A FIND:

Email me via my profile (click on my name) with the answers to these questions:

Are the structures of the three stones roughly the same? i.e Are the smaller pebbles in the stone structure about the same size on all the stones

What do you think could have caused the smaller pebbles embedded in the stones to become rounded?

You do not need to wait for confirmation from me before logging a find

Before this cache was created there was another geocache at this location - Harold's Stones - it was a neat hide which was sadly muggled.
So hopefully this new cache will bring people to this interesting location once again.

A Brief History Of Trellech:

---------------------------------------------------------------------------

During the Medieval period Trellech was one of the major towns of Wales, reported to rival Newport and Swansea in size. The remains of this settlement are currently subject to excavations which have been sustained over many years. It is most likely that the town was established by the De Clare family for the exploitation of local supplies of iron ore and charcoal, to provide weapons, armour and iron work for their military advances in Wales, including the building of Caerphilly Castle. Trellech was largely destroyed in 1291 as a result of a raid following a dispute over alleged deer poaching. The Black Death struck in 1340 and again in 1350 which affected the town very badly. Then in the Early 15th century the ravages of Owain Glyndŵr and his men further reduced the prosperity and in consequence the importance of Trellech, resulting in the village that you see today.

Harold's Stones:

-----------------------------------------------------------------------------------

The village of Trellech takes its name (tri=three, llech=flat stone) from the three tall stones set in a field close to the Monmouth-to-Chepstow road, standing in a line 12m (39ft) long. They are locally known as Harold's Stones, supposedly erected by Harold, last of the Saxon kings, in commemoration of a victory over the Britons in 1063. But Harold's Stones were erected over 3,500 years ago, long before Harold’s time. Another tradition says that the three stones mark the spot on which three chieftains fell in battle with the Roman Harold, who defeated the Welsh in Gwent. According to yet another legend, these stones were flung or thrown from Ysgyryd Fawr (Skirrid mountain), 23km (14mi) away, by the mythical giant Jack O'Kent. The first reference to these stones dates back to 1689, when Edward Llwyd mentioned them in Parochialia. In the same year Harold's Stones were carved on a remarkable sundial, now in Trellech's St Nicholas church. The sundial also bears some mysterious numbers: 7, 10, 14, which may be the stones' former heights in feet. Today Harold's Stones measure 2.7m (9ft), 3.7m (12ft) and 4.6m (15ft). The alignment runs NE-SW and it is one of the very few in this part of Wales. The stones, formed of a concretion of siliceous pebbles in a calcareous bed known as pudding-stone, lean at different angles. The largest stone is also the southernmost and the central one has two large cup marks on its south side which looked towards the midwinter sunset. The purpose of Harold's Stones is still unknown; they probably date from the Middle to Late Neolithic Period.

Pudding-Stone:

--------------------------------------------------------------------------------

Pudding Stone is a conglomerate which is a rock consisting of individual clasts within a finer-grained matrix that have become cemented together. Conglomerates are sedimentary rocks consisting of rounded fragments and are thus differentiated from breccias, which consist of angular clasts. Both conglomerates and breccias are characterized by clasts larger than sand (>2 mm).

Examples of Breccias and Pudding Stone can be seen in the images below.

Origin

------------------------------------------------------------------------

The stones are thought to be sourced from the local area since Pudding Stone is quite common around this part of the wye valley, nearby on Coppett Hill there is another Pudding Stone related cache, GC3HNA0.

Happy Earthcaching.
