Okay kiddo, do you know what a city is? It's a big place where lots of people live and work together! But sometimes, cities can get too busy and crowded, which can make things hard for people who live there.
That's where urban planning comes in! It's like a big puzzle where people try to figure out how to make a city work well for everyone who lives there.
In Barcelona, there are lots of things that people think about when they're planning the city. One thing they focus on is making sure that there are lots of different kinds of spaces for people to use. There are big parks where you can run around and play, little side streets where you can walk and look at cool buildings, and big squares where you can get together with your friends and family.
Another thing people think about is how to make it easy for everyone to get around. In Barcelona, they have lots of different ways to get around, like buses, trains, and even bicycles! This is important because if people can get around easily, they can go to work, go to school, or go see their friends without getting stuck in traffic or feeling too tired.
Finally, people who plan cities think about how to make the city look nice, too. Barcelona is really famous for its unusual buildings, like the Sagrada Familia church, and the Park Guell with all its colorful tiles! They also try to make the city feel safe and welcoming for everyone who lives there.
All of these things can take a lot of planning and effort, but if it's done well, it can make a city like Barcelona a great place to live and visit!
