Mozart's Grave, Vienna
It's not known exactly where Mozart was buried but most people think it is somewhere in St Marx Cemetery. Its fairly easy to spot the grave, just head up the main avenue and it'll be on your left.
To get here, take tram number 71 from Schwarzenbergplatz and get off at the St Marx stop. Head up towards the bridge and after a bit you will see a sign to the cemetery heading off to the right, from here it is well signposted.
Visit the Mozart memorial in the St Marx Cemetery. He was buried in a paupers grave but there is a stone where they think he was buried. He was buried during a two year period when re-useable coffins were used and people were buried in mass graves so there is no personal grave. It seems a very strange and sad quirk of chance that one of the worlds most brilliant compsers last resting place is uncertain because he just happened to die in that two year period.
Mozart was buried in an unmarked grave when he died in 1791, but eventually a new one was made for him. He is buried in St. Marxer Friedhof. Just walk in the main gates and there is a sign pointing you in the direction of Mozart's grave.
I also think I saw a ghost there. There is a building just inside the gates and a little girl in a white dress opened a window on the bottom floor, looked out, and closed the window. It was way too out of place for it to be real. It was also past the hours of the cemetary and there was nobody else on the grounds. Thats the LAST time I go into a cemetary after it is closed.
A lovely old cemetery. A ways out of the city center, but worth the trip. You can take the U to get within a few blocks. It's free and open till dusk.
