From gorgeous seaside towns and villages such as Tenby and Colwyn Bay to the rugged mountain vistas and greenery of Snowdonia National Park, it’s easy to see why so many people fall in love with this amazing country.

But how much do you really know about Wales? To help you learn more about Cymru (the Welsh name for Wales, which roughly translates as “fellow countrymen”), here are several interesting Wales history facts you may not have been aware of.

This post is about seven Wales history facts.

Wales History Facts

Wales History Facts: Wales Population

People often ask, “Is Wales a country?” and we can emphatically say that, yes, Wales is indeed a country, and it’s bigger than you may have thought. Wales officially became a country with Henry VIII’s Act of Union in 1536. Before that, it was a loose collection of Welsh kingdoms.

Although Wales looks relatively small compared to the rest of the UK, never underestimate how much the Welsh Dragon can do given a little space!

Wales has a population of roughly 3.1 million, around 4.6% of the rest of the UK.

Another question that comes up is, “Is Wales in England?” No, Wales and England are separate countries, although they are neighbors and are both part of the United Kingdom. Wales has a Celtic past going back before Roman times, while England’s history began with Anglo-Saxon tribes invading the island of Great Britain in the 5th century. In the present, the countries of Wales, England, Scotland, and Northern Ireland make up the United Kingdom.

Wales History Facts: Wales Cities

Despite having some of the most stunning woodland, countryside, mountains, and coastal regions in the world, Wales still has plenty to offer those who prefer more of an urban setting.

When you want to hit the shops for some retail therapy, enjoy the world-famous Welsh culture, or learn more about Welsh history, you’ll be interested to know that Wales currently has seven cities. These are:

• Bangor
• Swansea
• Wrexham (thank you, Ryan Reynolds, for putting Wrexham on the map for our overseas friends)
• St. Asaph
• St. Davids
• Newport
• Cardiff (the capital city of Wales)

“Why only seven cities?” you may be asking if you’re on the other side of the pond. That is because, in the United Kingdom, a town becomes a city if it receives an official document from the monarch recognizing it as a significant urban area for various reasons (there are no specific criteria).

You may also be surprised to learn that Wales did not have a definite capital until 1955—and Cardiff had to fight off other competitor cities to earn its capital status!

One of the World’s Oldest Trees is Found in North Wales

One of the more interesting North Wales history facts you’ll read about today is that one of the oldest living trees in the world is located there, in Conwy, to be precise. Locals call the tree the Llangernyw Yew.

The tree dates back to the Bronze Age, and historians estimate it to be between 4,000 and 5,000 years old.

You’ll quickly discover that Wales history and culture are something the Welsh take great pride in. Given Wales’ Celtic roots, we can understand why. The ancient tree is steeped in superstition and is associated with Halloween and an ancient spirit known as Angelystor.

According to legend, the spirit appears under the tree each Halloween and utters the names of those destined to pass away before Halloween the following year.

Wales is a Castle-Lover’s Dream Location

When reading about the Welsh history timeline and Wales history facts in general, you’ll quickly discover that the country is home to many castles. By a lot, we mean more castles than anywhere else in Europe per square mile.

Wales is home to over 600 castles, so no matter where in the country you are, you’re never far from one of these amazing feats of architecture and engineering.

In North Wales? Why not head to Conwy after visiting one of the oldest living trees and take a tour of Conwy Castle?

Are you in South Wales and looking to brush up on your South Wales history facts? If so, make sure to make your way down to the nation’s capital and visit Cardiff Castle while you’re at it. However, Chepstow Castle in Monmouthshire is the oldest castle in Wales (and all of Britain). It was the Normans who began constructing this castle in 1067.

Eryri (Snowdonia) is the Perfect Outdoor Destination

Eryri National Park (previously known as Snowdonia National Park) was given national park status in October 1951, becoming the United Kingdom’s third national park. It’s one of the most gorgeous National Parks in the world, let alone the UK.

Located in northwest Wales, Snowdonia features amazing glacial landforms, mountains, panoramic vistas, woodland and forests, lush green fields, lakes and rivers, and, of course, the country’s tallest mountain, Snowdon. The mountain is called “Yr Wyddfa” in Welsh.

For those who love mountain biking, hiking, and rock climbing, Snowdonia is a part of the country you simply must visit. At 1,085 meters, Snowdon is the tallest mountain in Wales and also the tallest in Great Britain (outside of Scotland). It is also home to the historic Snowdonia National Railway, which will take you to the mountain’s summit.

North Wales is Home to Europe’s Longest Zip Line

Another one of Wales history facts you may not have been aware of is that it’s home to one heck of a large zip line.

Just a stone’s throw away from Snowdon, on the edge of Snowdonia, you’ll find the town of Bethesda, home to Zip World outdoor activity and adventure park, and Velocity, the world’s fastest zip line and the longest in all of Europe. The adventure park began as Treetop Adventures in 2007 and became Zip World in 2013.

Those brave enough to tackle it will zip line 1,555 meters, 500 meters above Penrhyn Quarry Lake, at speeds of up to 100mph. If you can force yourself to open your eyes, you’ll enjoy breathtaking views of Snowdonia and the surrounding countryside.

Zip World has locations across Wales (and the UK) and offers other attractions. These include forest coasters, bungee jumping, zip safari, cave trampolining, underground golf, rock climbing, soft play, and plenty more.

Wales is the World’s Only Country to Feature a Complete Coastal Path

If you love exploring the coast, you’ll love Wales. It’s that simple! Wales features some of the most breathtaking coastlines you’ll ever see. Furthermore, if you enjoy exploring the coast, another of many Wales history facts you’ll find especially intriguing is that Wales is the only country in the world to feature a complete coastal path. The Welsh government completed the construction of the path in 2012.

Coastal hikers will find a continuous waymarked path spanning the entirety of the country’s coastline. Providing 870 miles of uninterrupted coastal views, you’ll begin in the south, in Chepstow, before finishing in the north near the English border of Chester (or vice versa).
