Graz is in southeast Austria, and has a UNESCO World Heritage Site that is considered by many to be the best preserved medieval city centre in Europe. This region has lots of green space and beautiful trees. Old Town is the most popular tourism attraction here. Graz is culturally rich with numerous historically important buildings and landmarks. The opera house is a must see. The Museum of Art is great! There is too much to describe here, but believe me, this is a great vacation destination.
