I finally went out for sight seeing since my settled down here in the mid May. Where? Centrum of Ostrava? No. Poruba? No. Just inside the University. I sneaked into the Geological Science Faculty's geo-pavilion, where you can enjoy various mineralogical samples and fossils. I found .03 carat diamond there. Nobody is there. No camera. Maybe. I spent there almost two hours and enjoyed those kinds of stuff from the first to the third floor. I did not know Czech had an oil field. I really enjoyed this sight seeing inside the University.
