Are you sure that the name of the city isn´t Linz? ( yeah
without the "t"). Linz is the capital of Upper-Austria ( one of the 9 Austrian provinces)
Linz has a population of about 190 000.
....if the word Lintz would be right, I don´t know where this
city could be.
on www.linz.at you can visit Linz. ( Unfortunately it is in German).
I hope I could have helped you a little little bit.
And sorry for my English, I learn it at school
