Graz, the second largest city in Austria, is known as a student city because it has six universities with more than 44,000 students.
One if its most famous students was Nikola Tesla, the namesake for the all-electric sports car on the market today. He studied electrical engineering at the Polytechnic in Graz in 1875.
Graz is also home to the Lurgrotte, the most extensive cave system in Austria, which was discovered on April Fool’s Day (April 1) in 1894.
The cave entrance has a fossilized skeleton of a cave bear, (a species that died out 20,000 years ago) it’s also home to 600 bats, which are very much alive. I wanted to go in for an adventure, but it was closed at that time.
