Castle History

Before we ever stepped inside, this castle had already lived many lives. Some parts date back to the 12th century, others to the 1500s — and its walls have witnessed everything from grand gatherings to quiet decline. Much of its history has been lost to time, but every now and then, it reveals a little more. We’ve uncovered some fascinating details, but there’s still so much we don’t know. If you’re a local historian, a former visitor, or just someone with a memory or mystery to share — we’d love to hear from you. The castle still has secrets, and we’re listening.

Centuries of evolution

Late 11th Century:

Penllyn Castle was constructed by Robert Fitzhamon, a Norman lord, after the conquest of South Wales. It was likely built as a motte-and-bailey structure with a wooden keep, similar to other contemporary castles like Ogmore Castle.

12th-14th Century:

The castle was part of the Fitzhamon family's lands. Over time, the structure evolved into a stone fortress, possibly with a tower and defensive features to adapt to the shifting political climate of medieval Wales.

15th Century:

Penllyn Castle saw some changes, including likely repairs and modifications due to conflicts and evolving military needs. There is no clear documentation of major alterations during this period, but it continued to function as a stronghold.

17th Century:

By this time, Penllyn Castle had fallen into decline. Historical records from the period suggest that it was no longer a primary residence and had become largely in ruins.

18th Century:

The estate was redesigned, and the remains of the castle were integrated into a new mansion, with parts of the original medieval structure incorporated into the Georgian design. This phase likely involved the construction of a new house, built by Miss Emilia Gwynette between 1789 and 1804.

19th Century:

The structure underwent further transformations. Notably, new chimneys, water towers, and a service wing were added, particularly between 1860 and 1875. The castle and mansion were expanded with features typical of Victorian architecture.

20th Century:

The castle, though still grand, had experienced significant decay by the 20th century. The mansion continued to serve as a residence, though it began to show signs of age.

21st Century:

The property, now in private hands, is known for its historical significance and continues to be a subject of interest for heritage preservation. In recent years, the castle's grounds and historic elements have been explored by various preservation efforts.
