There is a lot more to Croatia than the hot sun, cool sea and pebbled beaches. Those parts of Croatia are very special, but sometimes it can be just as fun to mix it up and do something a little different.

Croatia has 6 observatories where you can gaze at stars, planets and comets through high-powered telescopes or on the dome of a planetarium. Some are well positioned on top of mountains giving you an excellent vantage point for watching the stars with your naked eye.

For those living in Croatia, many of these space observatories offer school programs for children to educate them about science, math, astronomy and technology.

In this post, we’ll cover:

  • Where you can find these observatories and planetariums in Croatia
  • Which programs they offer
  • Why you should visit

The planetarium of the Technical Museum of Nikola Tesla (TMNT) offers a projection of the starry sky inside of the dome. This simulation contains  approximately 5000 stars, from the equator to the North Pole. This is done using 31 optical systems. Each of them projects a different part of the sky.

Special projectors are used to show the Sun and the moon, planets, the Milky way, and other occurrences in the sky. It is also possible to simulate the daily movement of the starry sky to see its look at any time of the night and year from different geographical latitudes.

Tours are available individually and in groups Group tours are available in Croatian and English languages. Scientific lectures are occasionally held there.

The TMNT’s price list for 2020 is available here.

Address: Savska cesta 18, 10 000 Zagreb

Hvar observatory is used for scientific research in the fields of astronomy, astrophysics, geodesy, and geophysics, and is also used in the education of young scientists.

The observatory is situated above the town of Hvar in the historic fortress Napoljun. Napoljun was built by the French army during the Napoleonic Wars in the 19th century.

The observatory has 3 telescopes: a solar telescope, a stellar telescope, and an Austro-Croatian Telescope.
