You'll probably see Freising Cathedral from a distance before you actually find this important religious building. Rest a while inside if the doors are open or just admire the facade from outside.
This principal church is on the to-do lists of many visitors to Freising. But Freising Cathedral isn't the area's only highlight. Weihenstephan Brewery, Weihenstephaner Perennial Gardens, and Asam Theater are some other worthwhile attractions close by.
