Zagreb’s little known observatory is where you should head to make use of all those wishes you’ve been stockpiling over the years. It is located in the picturesque surroundings of Gornji Grad (upper town). The building continues to be a key post for scientific observation of natural astronomical phenomena, and regularly hosts visitors – both young and old – looking for a peek at stardust. It is open to the public in the evenings (Tuesday through Friday), when, in case of favorable weather conditions, telescopic observations are arranged with expert explanations. Admission is free.
