During the Wars of the Roses in the 15th century, the Griffith family’s allegiance shifted between the warring factions of Lancaster and York, adding another layer of intrigue to the castle’s history. The political turbulence of the era affected Penrhyn Castle, and it was not uncommon for it to be involved in the strategic maneuvers of Welsh and English noble families.
The Transition to the Pennant Family
In the 17th century, the estate passed to the Pennant family, marking a significant shift in the castle’s history. This period saw Penrhyn transform from a mere fortress into a more comfortable home, albeit one that still retained some elements of its defensive structure. The Pennants were a wealthy and influential family with extensive interests in the local economy, particularly in slate mining.
It was under the Pennant family that the foundation for the grand castle of today was laid. During the 18th century, Sir Charles Pennant began to accumulate wealth through slate quarrying in the region, particularly through the successful operation of the Penrhyn Slate Quarry, one of the largest slate quarries in the world. The Pennants’ growing wealth and influence would eventually provide the means for the castle’s complete transformation into the stately home that we see today. shutdown123
