Pembroke Castle

Pembroke Castle is one of the most impressive and best-preserved medieval fortresses in Wales, standing proudly above the Pembroke River since the 11th century. Most famously, it was the birthplace of Henry Tudor in 1457 — the man who would go on to defeat Richard III at Bosworth Field and establish the Tudor dynasty that shaped English history forever. The castle's enormous circular Great Keep, standing 75 feet tall with walls 19 feet thick, is a truly awe-inspiring sight and one of the finest examples of Norman military architecture in Britain. Visitors can climb to the top for sweeping views across the town and estuary that make the effort thoroughly worthwhile. Beyond the keep, the castle complex is vast and wonderfully explorable, with towers, dungeons, a great hall, and the extraordinary natural cavern known as the Wogan — a huge cave beneath the castle that once served as a watergate and boathouse. Costumed guides and interactive exhibits bring the history vividly to life, making it a superb experience for visitors of all ages. The castle hosts regular events throughout the year, including medieval re-enactments, jousting tournaments, and themed weekends, so it's worth checking what's on during your stay. Guests staying at Pen Mar Guest House in Tenby are perfectly placed to make a day trip to Pembroke Castle, which lies just a short drive west along the A477. It's well worth combining with a wander around the charming historic town of Pembroke itself, with its independent shops and welcoming cafés. Arrive early in peak season to beat the crowds and give yourself plenty of time — there's far more to see here than many visitors anticipate.
