The Botanical Garden of the University of Wrocław was founded in 1811. It is located on the north side of the cathedral of St. John the Baptist and the church of the Holy Cross, partly within the historic Ostrów Tumski, about 2 km from the Market Square. There are about 7.5 thousand species of plants in the garden. Of the trees growing in the Garden, 27 of them were recognized as nature monuments: oaks, yews, gingko, beeches and plane trees. In addition to the exhibition of plants in the Garden, the visitors can admire the geological cross-section of the Wałbrzych hard coal deposits built in 1856 in the rock garden, separated by sandstone and slate deposits. The garden is open to visitors from April 1 to November 30.
