The Botanical Garden of Hamma is a large public garden located in the heart of Algiers, the capital city of Algeria. It was established in 1832 during the French colonial period, and has since become a popular tourist destination and a landmark in the city.

The garden covers an area of over 30 hectares, and is home to a diverse collection of plants from all over the world. There are over 1,200 species of plants, including rare and endangered species, as well as a large collection of tropical and subtropical plants. Some of the most notable species in the garden include palm trees, cacti, orchids, and succulents.

In addition to its impressive plant collection, the Botanical Garden of Hamma is also home to several historical landmarks and buildings. The most notable of these is the Moorish-style villa known as the Palace of El-Hamra, which was built in the 19th century and is now used for official government functions. The garden also includes a small zoo, a lake with paddle boats, and several picnic areas.
