Graz Cathedral and Mausoleum

The cathedral of St. Giles dates to the 15th century. The 1st picture is in the nave looking at the high altar. This cathedral was built by Frederick III.
Of more interest to me is the mausoleum of Ferdinand II located on the same plaza. All the remaining pictures of this post are in the mausoleum.
The building was begin in the 17th century and has a complex history. I found it unusual as I visited, and that is because it began as 2 buildings: a church consecrsted to St Catherine of Alexandria and the burial chapel of the emperor.
The 2nd picture is what you see upon entering: the Catherine altar. The 3rd picture is of the burial chapel that is to the right of the Catherine altar. The crypts are below the burial chapel.
The 4th picture is the Mary altar to the left of the Catherine altar. The final 2 pictures are if parts of the ceiling.Okumaya devam et
