Cieszyn is an important centre of the electromechanical industry. It is also
the site of the Olza Cieszyn sweets factory (where the famous Prince Polo
wafers are made) and the Brackie Browar, where Żywiec Porter is brewed. The
main source of income for many citizens is trade with the nearby Czech Republic
and retail trade associated with transit across the two bridges over the Olza
to Český Těšín
