Barcelona is a city in Spain, considered to be one of the best cities in the world. It has been the capital of Spain for over 500 years and is the second largest urban area in Spain. It is located in the Mediterranean basin, close to the French border. The city is composed of many neighborhoods, called barrios, which are in turn divided into districts, called espots. The main neighborhoods of Barcelona are Montjuïc, Barri Gòtic, Eixample, Gràcia, Sant Boi de Llobregat, Sant Antoni Despí, Villa Dolè, and the Eixample Village. These neighborhoods, together with the surrounding areas, form the urban core of Barcelona.

The Barcelona a la butxaca app is the official mobile application of the Barcelona City Council. It offers the main municipal services for citizens in a single access point.
