Tre'r Ceiri is a truly spectacular hillfort dating back to the Iron Age. In English the name means 'town of the giants.' A giant of a hillfort it is too and one of the best preserved of all with stunning views across the Llŷn Peninsula.

The settlement is surrounded by stone walls that are amazingly largely intact. Some of these walls are four metres high in places. Inside the fort are the remains of around 150 houses which in days gone by would have had turfed roofs.

A truly amazing place to visit!
