10 Most Famous Buildings In Wales

Wales and Welsh identity established itself after the Romans left Great Britain in the 5th century.

The country is part of the United Kingdom and is considered to be one of the modern Celtic countries in the world along with Scotland and Ireland.

The country has had a rocky history and the Welsh parliament was only established in 1998 after being incorporated into the English legal system since the 16th century.

The cultural identity of the people living in Wales never left, something emphasized by the fact that both Welsh and English are the official languages of the country.

The history of Wales and the rest of the United Kingdom is closely tied, and even though it’s not considered to be a major tourist destination, there are still some amazing landmarks in Wales that you have to visit one day.

In this article, we’ll take a closer look at the most famous buildings in Wales so you can add these items to your bucket list when you plan to visit the country.

1. Conwy Castle

Conwy Castle is arguably one of the most iconic castles in Europe and is one of the Welsh castles that was built by King Edward I (1239-1307) during his conquest of Wales between 1283 and 1289.

The castle was listed as a UNESCO World Heritage site in 1986 and was described by the organization as one of the “finest examples of late 13th century and early 14th-century military architecture in Europe.”
