On our way from Salzburg to Prague we made a stop over in Linz. We only spent one night in Linz but managed to go out early in the evening. On our way over to the Altstadt, we came across the Cathedral of the Immaculate Conception, the largest church in Austria with 20,000 seats. Besides its size, the stained glass windows are remarkable. One particular window is the Linz Window, which is famous for portraying the history of Linz.
