There are currently two helpful tourist offices, though a reorganisation is mooted which might combine them. The central branch is right on the main square. It offers a useful free brochure but you might consider paying €2.50 for the more detailed Strolling through Breda walking tour which has 10 pages of extra detail in each of three languages. A second office on Willemstraat is handy for the train station.
In Dutch, the free Breda City App for mobiles or the website www.stappen-shoppen.nl both have masses of useful information including a what's-on guide.
