I liked your post very much, I know about this cathedral and I passed by it but I never went inside, if I'm not mistaken there is a bike library next to it.
On my next visit to Szeged I will definitely stop here.
By the way, did you go to the sausage festival this weekend in Turija?
I wanted so much to get there but unfortunately my plans have changed lately and I didn't make it, maybe next time.
