Dorotheum was founded by emperor Joseph the first and is with its over 300 years the oldest auction house in the world.
I have never been there, so when Igersvienna on Instagram announced that 15 lucky people will have a tour I knew I wanted to be a part of it.
From very modern art, for example this huge sculpture of a floating potato (worth around 80,000-100,000€!!) to jewellery and pictures, you can find lots of lovely items.
If you have the necessary pocket money!
