Vendraith Vawr is half a mile of." - Leland, Itin. tom. v.
p. 22.
{96} The scene of the battle fought between Gwenllian and Maurice
de Londres is to this day called Maes Gwenllian, the plain or field
of Gwenllian; and there is a tower in the castle of Cydweli still
called Tyr Gwenllian. [Maes Gwenllian is now a small farm, one of
whose fields is said to have been the scene of the battle.]
{97} The castle of Talachar is now better known by the name of
Llaugharne.
{98} Much has been said and written by ancient authors respecting
the derivation of the name of this city, which is generally allowed
to be the Muridunum, or Maridunum, mentioned in the Roman
itineraries. Some derive it from Caer and Merddyn, that is, the
city of the prophet Merddyn; and others from Mur and Murddyn, which
in the British language signify a wall. There can, however, be
little doubt that it is derived simply from the Roman name
Muridunum. The county gaol occupies the site of the old castle, a
few fragments of which are seen intermixed with the houses of the
town.
{99} Dinevor, the great castle, from dinas, a castle, and vawr,
great, was in ancient times a royal residence of the princes of
South Wales. In the year 876, Roderic the Great, having divided the
principalities of North and South Wales, and Powys land, amongst his
three sons, built for each of them a palace.
