The active trend socially and economically drew the city out of its walls and at the end of the thirteenth century another wall was built around the new settlements known as viles noves (new houses). Around the 14th century another stretch of walls began to be constructed. Architects such as Antoni Gaudi in the latter half of the 19th century planned extension of the city on a rigid grid system (History of Barcelona).
The grid system occupies space in the form of artistic constructions and wide roads. While this raises the aesthetic feel it aggravates the requirement of modern constructions where space is at premium (Architecture).
Today the city of Barcelona is fabulous and one of the costliest in the world to live in. It has beautiful buildings, a university, museum, wide roads, hotels, and golf courses. The city is a marvel and it beckons the world from its pristine Mediterranean shores.
