Ok, so technically, it's got a couple different styles since it was added onto over time, but when I picture gothic churches, I picture massive stone pillars and detailed carvings, of which this church had many. So, in my very un-expert opinion, it's gothic. In any case, this is the outside of the church at night. The other side of the roof has two Austrian eagles instead of the zig zag pattern. The church was first built in 1160.
When you first walk in, you notice two things: this church is long (351 feet long) and it has weird colors cast about due to the lack of stained glass windows. The windows survived WW2, but just after the German troops retreated, a massive fire started in Vienna (along with a bit of looting by locals) and the fire took out the church windows. Most of the other important features in the church survived the fire, because they had brick barriers built around them. The church also was heavily damaged, but when it got repaired and re-opened, they put up patchwork colored glass that makes the inside of the church look like either the colored cellophane that wraps Easter baskets or a tie dye experiment gone wrong.
