The last observatory we visited in Croatia was the Rijeka Observatory. It's a 4.5 km walk from city center or it's possible to take the bus 7A to the observatory. They have a Cafe on top of the observatory with a panorama view. Even a planetarium.
Here is my report from the observatory:

Later I will have more photos, it will be sent to me from their archive. I make a notice when they are online.
We got a lot of exiting things to see in Croatia !
