If you stand in the main square in Subotica, you are surrounded by huge stripey buildings. The biggest one is the City Hall - a tall building with a roof covered in green and yellow patterned tiles. Inside, the ceilings are painted blue and gold like a fancy cake.
Subotica's people come from many backgrounds. Some families have spoken Serbian for hundreds of years. Some speak Hungarian as a first language. Others speak Croatian or other languages. Walking through the market, you might hear all of them mixed together in a single hour.
Just outside the city is a long lake called Palic, with sandy beaches, swans and rowing boats. In summer, families spend whole afternoons there. There is also a small zoo with a famously lazy hippo.
Many of Subotica's grand buildings were finished about 120 years ago, when builders all over Europe were experimenting with this 'flowery' Art Nouveau style. Few European cities now have so many of them so close together - Subotica is one of the best places in the world to see them.
