Sometimes called the "Land of Castles" and "Castle Capital of the World," Wales once had about 600 castles. Many of these Welsh castles are now in ruins, while others are open for tours or even overnight stays. Since the castles were usually built on cliffs and hillsides, those who climb their often steep stairways are rewarded with spectacular views of the surrounding countryside. Most of the castles have been destroyed and rebuilt several times through the embattled history of the country, an enchanting destination often overlooked by travelers to Great Britain.

Visitors to Wales might notice the seemingly unusual spellings of the castle names and Welsh cities, so here's a little about the fascinating ancient language of the country. The Welsh language (Cymraeg in Welsh) is Celtic in origin and thought to have been spoken as early as 600 B.C. The alphabet uses 29 letters that include "ll","ff", and "dd" which explains why they are often seen in Welsh words and names of castles ("castells" in Welsh). The language is still spoken in Wales, along with English, and it is taught in most Welsh schools to support its survival. When you travel to Wales to enjoy its scenery, beaches, forests, and of course, its castles, you might also notice its national emblem of daffodils.

Thought to have been constructed by the Normans in the late 11th century to defend Cardiff, Castell Coch ("Red Castle") overlooks the Taff Gorge on the northern boundary of the city. The original castle was destroyed, probably during the Welsh rebellion of 1314, and many centuries later, it was rebuilt in the Victorian style on its medieval site. Today, visitors can explore the restored interior of the castle as well as the surrounding areas on the Taff Trail, surrounded by ancient beech trees of the Fforest Fawr.

Cardigan Castle

This 11th-century castle, located on the River Teifi, combines ten centuries of history with the present day.

The first National Eisteddfod, now an annual celebration of Welsh culture, was held in 1176 to mark the completion of the castle by Lord Rhys.
