Barcelona is Spain's second largest city and the capital of Catalonia, one of the 17 regions that form Spain. The city has a wealth of unique historic architecture and has emerged as one of the most popular tourist destinations in Europe during the 1990s.
A relatively small percentage of travelers to Spain are targeted by pickpockets each year, so please be careful with your personal belongings.

August is an excellent month to go to Barcelona, you'll find cheap accommodation and a much quieter city... it's easy to understand, a vast majority of Spaniards go on vacation in August. Business is low, people from Barcelona tend to be on vacation, hotels that remain open but don't have their business customers tend to lower prices and make offers. And Barcelona has decent enough beaches... Though the people in Barcelona will really appreciate that visitors do not consider it a beach resort and keep decent clothes on, specially when visiting churches, etc...
