The Padua Botanical Garden, also known as Orto Botanico di Padova in Italian, is a botanical garden located in Padua, Italy. Founded in 1545, it is the oldest academic botanical garden in the world still in its original location and is now a UNESCO World Heritage Site.

The garden covers an area of about 22,000 square meters and contains more than 6,000 plant species, including a vast collection of medicinal plants, rare and endangered species, and historical plants. The garden has been a center of scientific research since its establishment, and it played a critical role in the development of modern botanical science.

One of the unique features of the Padua Botanical Garden is its circular shape, which was inspired by the idea of a perfect world symbolized by a circle. The garden is divided into four parts, each representing a different theme: medicinal plants, useful plants, exotic plants, and ornamental plants.

The garden also includes several historical buildings, such as the Palazzo del Bo, which was the original headquarters of the University of Padua and now houses the university's natural history museum, and the Botanical Museum, which contains an extensive collection of botanical specimens, including specimens collected by Charles Darwin during his travels.

Visitors can explore the garden's many paths and walkways, admire its beautiful plants and flowers, and learn about the garden's rich history and scientific significance. Guided tours are available, and the garden hosts various events and exhibitions throughout the year.
