Caernarfon Castle

Built not far from a Roman fort, the first motte-and-bailey castle at Caernarfon was made of wood and used soon after 1088. 

In 1293 Edward I ordered the construction of a stone castle to replace the existing structure. 

As the administrative centre of North Wales, the castle and its town were built on an impressive scale. Although the castle itself just took an astonishing five years to build, completion of the town walls took until 1330. In addition, some planned aspects, such as the King’s Gate, were never completed.

Edward II was born at Caernarfon on 25 April 1284. He became the first Prince of Wales in 1301, with control over Wales and its incomes.

Caernarfon Castle found itself under siege and attacked several times in the first 350 years. After the end of the english Civil War, it was never used for warfare again and fell into disrepair.

Much of the buildings within the castle walls have disappeared. However, the curtain wall and towers still stand. Therefore, Caernarfon was added to the UNESCO list of World Heritage Sites in 1986.

In June 1960 the Royal Welch Fusiliers Museum opened inside Caernarfon Castle. 


Llechwedd Slate Caverns

Located near Blaenau Ffestiniog in Gwynedd, Llechwedd Slate Caverns offer a glimpse of the historic slate quarrying industry. The Llechwedd Deep Mine Tour has the steepest narrow gauge railway in the UK and travels over 500 feet underground to the disused slate caverns, Meanwhile the Quarry Explorer Tour heads out to the furthest reaches of the Llechwedd site to explore the history of mining in the area.


Lloyd George Museum

Prime Minister from 1916 to 1922, Lloyd George was a notable politician who is still remembered today. The Lloyd George Museum operates in his childhood home.


Mary Jones World

In the year 1800, 15 year old Mary Jones walked 26 miles to buy a rare Welsh language bible from Thomas Charles. 

This heritage centre informs visitors about Mary Jones, Thomas Charles, and the growth of the British and Foreign Bible Society.


National Slate Museum

Located at the disused Dinorwic slate quarry, within the Padarn Country Park, Llanberis, Gwynedd, this visitor centre makes use of the 19th-century workshops to commemorate an industry which once employed 17,000 Welsh men.


Penrhyn Castle

Although much of the current mock-castle house was built between 1822 and 1837, a staircase from the previous manor house, which was crenellated under licence in 1438, is still intact.


Penrhyn Castle Railway Museum

One of the attractions of National Trust property Penrhyn Castle, the railway museum houses narrow-gauge locomotives and other artifacts from the age of steam.


Segontium

Founded by Agricola, the Roman fort of Segontium was garrisoned by Roman auxiliaries from present-day Belgium and Germany until the end of the Roman occupation of Britain. Visitors can find the site on the  outskirts of Caernarfon and see the foundations.


Sygun Copper Mine

The Sygun Copper Mine was part of an important mineral industry throughout the industrial revolution, but closed in 1903. Since the 1980s the site has been run as a private tourist attraction, and offers a museum and art gallery in addition to visits into the mine.
