The Chester and Shrewsbury Railway intersects these two ancient dykes. At the junction of the branch line to Brymbo, Minera, &c., the railway crosses Watt’s Dyke, and continues to run on the left side of it, travelling from Chester, for about fourteen miles, until Gobowen is reached, where the line again crosses the dyke; the superintendants of modern improvements, especially railway engineers and contractors, paying little if any deference to mere antiquities. By this route the railway traveller passes a considerable distance on the neutral ground, where alone, for many years, the trade and commerce of the Britons, the Saxons, and the Danes, were transacted. Offa’s Dyke at Brymbo is about two miles to the right, from Chester, and runs parallel with the railway for about eighteen miles. Churchyard, in his “_Worthies of Wales_,” thus chronicles, in his quaint verse, the use to which the “free ground” was applied in early days:— “Within two miles, there is a famous thing Called OFFA’S DYKE, that reacheth farre in lengthe; All kind of ware the Danes might thither bring; It was free ground, and called the Britaines’ strength. WATT’S DYKE, likewise, about the same was set, Between which two, both Danes and Britaines met.” For many years after Offa’s memorable defeat of the Britons on Rhuddlan Marsh, the history of the district conveys but little information interesting in the present day. “Wars, and rumours of wars,” are the only topics on which past historians have filled their pages in reference to this period. Rhodri Mawr (Rhoderick the Great), one of the most celebrated warriors and princes of Wales, succeeded to the sovereignty of North Wales and Powys in 843. In the year of his succession his territories were invaded by Berthred, King of Mercia, whom he defeated with great loss. Rhodri left three sons, and, according to the law of gavel-kind, he divided his dominions among his children. His son Mervyn had the principality of Powys, with the palace of Mathraval. His three sons were called _y tri thywsog taleithiog_, or diademed princes, from their wearing diadems of gold set with precious stones; and Anarawd, his eldest son, received a yearly tribute from the Prince of Powys. Contentions still continued, and intestine divisions kept the Britons in as violent commotion as if they were battling with their avowed enemies on the border. Mervyn did not long enjoy his dominion, as he was slain in 892 by his own subjects, headed by his brother Cadell, who took possession of the throne. The reign of Cadell was also brief, and his son Hywel Dda (Howel the Good) succeeded him. The Welsh Justinian, as Hywel has been called, died in 984, deservedly honoured by his subjects, and leaving four sons, all of whom perished in the desolating wars to which his country soon after fell a prey.
