Perched on a rocky peninsula overlooking the wide sweep of Cardigan Bay, Criccieth Castle boasts unrivaled views of the Llŷn Peninsula coastline.
This romantic and picturesque castle, with its twin-towered gatehouse, embodies the charm and mystique of Welsh medieval history, and was originally built by two of Owain Glyndŵr’s predecessors.
First Llywelyn ap Iorwerth (Llywelyn the Great) who a gatehouse and D-shaped stone towers before his grandson Llywelyn ap Gruffudd added the outer ward, curtain walls and two more towers.
When Edward I duly invaded control of the castle passed to him before the powerful medieval Welsh prince Owain Glyndŵr destroyed it and the town of Crricieth was controlled by the Welsh once again.
Visitors can now explore the castle grounds and imagine its former glory as a noble residence and stronghold.

This small but evocative castle, built by Llywelyn the Great in the early 13th century, stands on the shores of Llyn Padarn and provides a captivating glimpse into the history of Welsh princes and their struggle for independence.
A lone tower remains of the castle, built to protect the Llanberis Pass - the route inland from Caernarfon on the coast to the Conwy Valley.
It is well worth visiting as the setting inland - surrounded by the mountains of Eryri | Snowdonia National Park - is spectacular and a marked contrast to other Welsh castles on the coast.

Castell Dolwyddelan | Dolwyddelan Castle
Dolwyddelan Castle is perched dramatically on a hilltop near the village of the same name, picturesquely located near Betws-y-Coed on the road to Blaenau Ffestiniog.
This striking 13th-century fortress, associated with the legendary King Llywelyn the Great, is crafted from local stone meaning it blends seamlessly into the rugged surroundings.
Standing amidst breathtaking views of both mountains and valleys, Dolwyddelan Castle - just like Dolbadarn above - was built to protect a mountain pass.
By the early 19th century Dolwyddelan Castle was a romantic ruin popular with landscape artists.
The current incarnation is not all original though - the then Lord Willoughby de Eresby ‘restored’ the keep with medieval-style battlements which is what you see today.
Directions to Dolwyddelan Castle
The castle is found just off the A470 south of Betws-y-Coed, to the west of the village of Dolwyddelan.
The nearest parking is in a layby 500m away from which a public footpath leads to the castle.
