Cardiff (Welsh: Caerdydd) is the capital and largest city of Wales. It used to be an industrial city, but is now a lively and modern capital city and a tourism hot spot. The city is friendly to pedestrians, and summer is by far the best time to visit, with large festivals, and outdoor dining and drinking. The city centre has been intensely developed in the 21st century, and is now considered to be one of the top ten shopping destinations in the United Kingdom.
