Gothic quarter

There is a whole neighbourhood  very narrow streets where youc an get lost and maybe find yourself. You will see very nice squares eevrywhere. Also small shops, cafes, restaurants and a lot of interesting people. 

This is definitely oneof the best places to visit in Barcelona because is authentic and you will definitely enjoy every minute of it

Gothic Quarter is a small area full of Gothic buildings in the city centre. It took me only 15 minutes to walk around this area.

And the picture below is the Cathedral of Barcelona. It costs a few euros to get inside (so I didn't enter).

And there are a few museums in this area, but none of them is free of charge.
