Trim Castle

On a wet February day, we visited Trim Castle in County Meath, its ancient silhouette rising through the mist. Below us, the Boyne River was thundering, swollen with winter rain as it carved its way past the fortress walls. Trim Castle, Ireland’s largest Anglo‑Norman fortress, sits in the town of Trim in County Meath, just 45 minutes northwest of Dublin.
When visiting, you can wander the castle grounds for free, taking in the sweeping views and atmospheric ruins, or pay the entrance fee to explore inside. The 13th‑century gatehouse is especially striking: once the main point of controlled entry, it still bears the defensive features of its time—arrow loops, murder holes, and thick stone walls that whisper stories of watchful guards and long‑gone battles.

At the heart of Trim Castle stands its massive three‑storey keep, an unmistakable silhouette against the Meath landscape. Built in the late 12th century, the keep is a rare twenty‑sided design—an architectural quirk that makes it one of the most distinctive medieval structures in Ireland. Climbing through its narrow stairways and echoing chambers gives you a real sense of the fortress’s scale and the lives that once moved through its stone corridors.

Just beyond the keep lie the remains of the Great Hall, once the social heart of Trim Castle. It was here that feasts were held, visitors were received, and the daily life of the medieval lordship unfolded. 

Walking around the grounds, we admired the massive stone defensive walls, their weathered surfaces telling centuries of stories. We were lucky—on this particular morning, the sun finally made an appearance, breaking through the grey after one of the wettest Januaries and Februaries the area had seen.

The castle is managed by the Office of Public Works, which oversees many of Ireland’s most important heritage sites. And for anyone who follows our adventures, you’ll know by now that we have a soft spot for heritage sites—they’re always the first places we seek out.
