Botanical Garden of the Jagiellonian University (est. 1783) is the oldest such garden in Poland. It was set up on the site of an earlier garden of a palace from ca 1600 belonging to the Princes Czartoryski family. Frequently rebuilt and expanded, it boasts glasshouses including palm houses, and the Astronomical Observatory. Luckily it was undamaged in the Second World War, which allowed it to offer plants to similar institutions being reborn throughout the country. Today part of the University’s Institute of Botany, it houses around 5000 plant species and cultivars from all over the world.
