Historically, Spain has had quite a few capital changes. For example from 513 to 1561, Toledo was the capital. By the 1560s, however, all the hustle-and-bustle was happening in Madrid. This is why Madrid became Spain's capital (officially) in 1606. Think about that! It is over a span of 400 years that this wonderful city has transformed into what it is today.
As a result of those transformations, you can find a mixture of old and new. Some buildings look old, while others look new. Yet, Madrid is not only a 'concrete jungle.' It has a variety of different parks, trees, and green spaces. Basically, Spain's capital is the wondrous mixture of nature and concrete.
In the process of creating space for large cities, nature is damaged. Nonetheless, I find Madrid's metro system to be special. Once installed, the underground metro system helps preserve the external environment above ground. It reduces the number of people driving on the streets, which reduces pollution. In July, approximately 48,756,098 people used the metro!
Another thing that makes Madrid special is its parks. In total, Madrid's parks cover about 33 million square meters.
