Anja "anjaaustel" helped me to get all the unesco cards from Germany and she also helped me with this 2 from Austria, Graz and Semmering railway.
"Graz is the second largest city in Austria after Vienna. Politically and culturally, Graz was for centuries more important for Slovenes than Ljubljana, the capital of Slovenia, and still remains influential.
The old town was added to the Unesco World Heritage List in 1999 due to the harmonious co-existence of typical buildings from different epochs and in different architectural styles. Situated in a cultural borderland between Central Europe, Italy and the Balkan States, Graz absorbed various influences from the neighbouring regions and thus received its exceptional townscape. Today the old town consists of over 1000 buildings, their age ranging from Gothic to Contemporary." - in: wikipedia
"The Semmering Railway, built over 41 km of high mountains between 1848 and 1854, is one of the greatest feats of civil engineering from this pioneering phase of railway building. The high standard of the tunnels, viaducts and other works has ensured the continuous use of the line up to the present day. It runs through a spectacular mountain landscape and there are many fine buildings designed for leisure activities along the way, built when the area was opened up due to the advent of the railway." - in: www.whc.org/en/list/785
