The plant capitals of Graz’s Leechkirche, dating from the late 13th century, reveal a unique blend of natural observation, symbolism, and medicinal knowledge. Botanically identifiable plants such as lily, ivy, fig, and mallow are intricately carved in stone, reflecting a medieval worldview that saw nature as divine and healing. These capitals are not merely decorative but express spiritual and therapeutic significance, rooted in the hospital tradition of the Teutonic Order.
