5 Hryven Lviv University Astronomical Observatory

The Lviv Astronomical Observatory, founded in 1769 under the Jesuit-run university, is one of the oldest continuously operating observatories in Eastern Europe. It survived the partitions of Poland, the collapse of the Habsburg Empire, two world wars, and Soviet reorganization — each regime finding the facility too scientifically useful to destroy. The observatory is particularly associated with work on variable stars and positional astronomy conducted through the nineteenth and early twentieth centuries.

Ukraine's commemorative bimetallic and base-metal collector series has issued dozens of institutional subjects since the late 1990s, with Zahreba cataloguing the steady expansion of that program.
