The most remarkable thing about the Castle is that for nine centuries, the building, the Berkeley family, the archives (which go back to the 12th Century), the contents, the estate and the town have all survived together.
Its place in history is significant, not just because it is still intact, but because the Berkeley family and their home have played an important part in the power struggles of so many centuries.
The Castle is one of the March Castles, built to keep out the Welsh.
It has all the trappings to match: trip steps designed to make the enemy stumble during an assault, arrow slits, murder holes, enormous barred doors, slots where the portcullis once fell, and worn stones where sentries stood guard.
It is also a fairytale Castle with its warm pink stone that glows in soft sunset light. Outside, the battlements drop some 60′ to the Great Lawn below; but inside the Inner Courtyard, the building is on a human scale, with uneven battlements, small towers, doors and windows of every shape and size. The surrounding land would have been flooded for defence.
