Trim Castle

About

Few places in Ireland contain more medieval buildings than the heritage town of Trim. Trim Castle is foremost among those buildings.

In fact, the castle is the largest Anglo-Norman fortification in Ireland. Hugh de Lacy and his successors took 30 years to build it.

The central fortification is a monumental three-storey keep. This massive 20-sided tower, which is cruciform in shape, was all but impregnable in its day. It was protected by a ditch, curtain wall and water-filled moat.

Modern walkways now allow you to look down over the interior of the keep – a chance to appreciate the sheer size and thickness of the mighty castle walls.

The castle is often called King John’s Castle although when he visited the town he preferred to stay in his tent on the other side of the river. Richard II visited Trim in 1399 and left Prince Hal later Henry V as a prisoner in the castle.
