Mariä-Empfängnis-Dom (Neuer Dom), or Cathedral of the Immaculate Conception (New Cathedral), in the city of Linz, Austria: plans for it were started in 1855, with the first stone laid in 1862 and it finally being finished in 1924 with a French High Gothic architectonic style. It also received in this year the function of cathedral of the city.
It was to be Austria's largest and highest cathedral, but the original plan was not approved, as in that time by law no building was allowed to be taller than the South Tower of St. Stephen Cathedral in Vienna: it still have the title of the largest one on Austria, being able to have 20.000 people inside of it, but the plan for the spire was reduced to 135m height, only 2 meters lower than the Cathedral of Vienna.
The interior is just massive, both in height and size: before entering it, I wasn't aware that I was to be the only one inside it, and of the darkness of the environment. Do not be deceived by the ligh in the photography: the church may have huge stained glass windows, but the light from the windows just dissolved after travelling some meters and add to that that the internal lights were off.
I am not very happy with it, but I managed to get this photo, with a trade-off in quality to rescue the shadows details and because of high ISO noise (@ 28mm, f/2.8, ISO 4000 and 1/15s handheld - yes, shame on me again, no tripod again).
