I live in Cadiz, Spain.
First,There are two different parts in my city. One of them is called "old city"where you can find monuments of various civilisations such as Arabian, Roman or Phoenician. You still can see a Roma house which you can visit. A lot of inmigration has taken place in last decade. Chineses came here. They live in neighbourhood which is called "little China" because the steets are full of Chinese restaurants and shops.
The other part of city is called "new city".It is moderner that other part.There are buildings, offices and shops.
Secondly,Cadiz it's a great place to live because a lot of reasons.Weather is very nice, it isn't too hot in summer and cold in winter other reason is that there is a beautiful beach.
In the end, one of place most important in Cadiz is its university which is one the most culturrally and etnically diverse universities of Spain. A lot of student come here. They study Spanish. They are from England, France , Finland...
If you meet with them you will learn about their culture, language, traditions..
