Is Trevecca, where Howel Harris, one of the founders of Welsh Methodism, was born in 1713, and where in 1752 he established a communistic religious "family" of about a hundred persons; their representatives in 1842 handed over the property to the Welsh Calvinistic Methodist connexion, who in that year opened there a theological college, and in 1874 added to it a Harris memorial chapel.
In the preface it is stated that Howel, "seeing the laws and customs of the country violated with impunity, summoned the archbishop of Menevia, other bishops and the chief of the clergy, the nobles of Wales, and six persons (four laymen and two clerks) from each comot, to meet at a place called Y Ty Gwyn ar Da y, or the white house on the river Tav, repaired thither in person, selected from the whole assembly twelve of the most experienced persons, added to their number a clerk or doctor of laws, named Bllgywryd, and to these thirteen confided the task of examining, retaining, expounding and abrogating.
Howel caused three copies to be written, one of which was to accompany the court for daily use, another was deposited in the court at Aberfraw, and a third at Dinevwr.
The bishops denounced sentence of excommunication against all transgressors, and soon after Howel himself went to Rome attended by the archbishop of St David's, the bishops of Bangor and St Asaph and thirteen other personages.
The laws were recited before the pope and confirmed by his authority, upon which Howel and his companions returned home."
All this could not have been effected before Howel had subjected Wales to his own rule, therefore not before 943.
Howel Dda, king of West Wales, Owen, king of Cumbria, Constantine, king of the Scots, and Ealdred of Bamburgh, and henceforth he calls himself "rex totius Britanniae."
"An old ruynous thinge," as the Elizabethan poet Churchyard calls it even in the 16th century, it was inhabited, apparently, about 1390, by Myfanwy Fechan of the Tudor Trevor family and beloved by the bard Howel ab Einion Llygliw, whose ode to her is still extant.
The chief buildings are the Carmelite Priory (ruins dating perhaps from the 13th century); a Bluecoat school (1514); a free grammar school (1527); an orphan girl school (funds left by Thomas Howel to the Drapers' Co., in Henry VII.'s reign); the town hall (built in 1572 by Robert Dudley, earl of Leicester, enlarged and restored in 1780); an unfinished church (begun by Leicester); a market hall (with arcades or "rows," such as those of Chester or Yarmouth); and the old parish church of St Marcella.
Howel, son of Cadell, commonly known as Howel Dda the Good, is ever celebrated in Welsh history as the framer, or rather the codifier, of the ancient laws of his country, which were promulgated to the people at his hunting lodge, Ty Gwyn ar Taf, near the modern Whitland.
The laws of Howel Dda throw a flood of interesting light upon the ancient customs and ideas of early medieval Wales, but as their standard of justice is founded on a tribal arid not a territorial system of society, it is easy to understand the antipathy with which the Normans subsequently came to regard this famous code.
