The Aktiengesellschaft Cologne Zoological Garden is the zoo of Cologne, Germany. It features over 10,000 animals of more than 850 species on more than 20 hectares. The internationally renowned zoo with an attached aquarium and invertebrate exhibit is active in preservational breeding of animals that are in danger of becoming extinct. In addition, in-the-wild conservation efforts and research focussing on animals of Madagascar, Wallacea, and Vietnam are actively promoted and supported via cooperation with Cologne University and local projects, such as in the case of Przewalski's horses. The zoo was founded in 1860. The world wars led to a phase of stagnation, and the zoo had to close for two years entirely, after virtually being destroyed in World War II. It reopened in 1947; the aquarium was added in 1971. In 1985, the large primate house, one of the main attractions, was opened. Today, the zoo also features a free-flight rainforest hall with free-ranging birds and reptiles opened in 2000, a large elephant park, a house for hippos with great underwater views, and as the latest addition, a farm with rare native species and petting zoo.

The Flora und Botanischer Garten Köln (11.5 hectares) is a municipal formal park and botanical garden located adjacent to Cologne Zoological Garden at Amsterdamer Straße 34, Cologne, North Rhine-Westphalia, Germany. It is open daily without charge. The garden dates to 1863 when a private company was organized to create Flora park (5.5 hectares) as a replacement for the city's older botanical garden near the Cologne Cathedral, which in 1857 was destroyed for construction of the central railway station. This new park was designed by Peter Joseph Lenné in 1864 in a mixed German style, incorporating French Baroque, Italian Renaissance, and English landscape garden elements. In its center is a glass palace (orangery) structure of cast iron and glass patterned upon the Crystal Palace (London) and Jardin d'hiver (Paris), which served as an exhibition site through the late 19th century, including horticultural exhibitions in 1875 and 1888, and an industrial exhibition in 1889. Frauen-Rosenhof, an art nouveau garden, was added in 1906. Between 1912 and 1914, as it suffered financial problems, the garden was acquired by the city, which in 1914 built an adjacent botanical garden (4.5 hectares). These two gardens were united in 1920, with new glasshouses and exhibition houses for exotic and tropical plants added in the 1950s. Flora park was restored in 1987, and today contains an Italian Renaissance garden with hornbeam pergolas, cascade, and the (since a couple of years restored) Flora Temple, surrounded by gardens in the English landscape style, as well as a heather garden, fern garden, fragrance garden, Mediterranean garden, and pond. It also contains a number of notable trees, some dating to the garden's establishment; more than 60 specimens have been designated natural monuments. The botanical garden cultivates nearly 10,000 types of plants, including approximately 2000 species in its alpine garden. It also contains good collections of magnolias, rhododendrons, coniferous trees, maples, and Hamamelidaceae, as well as a medicinal plant garden and farmer's garden of local crops. About 5,000 species are presented in four exhibition greenhouses: Main greenhouse – tropical rainforest plants. Small tropical house – tropical crops including bamboo, cinnamon, cocoa, coconut palm, coffee, pineapple, sugar cane, and vanilla, plus water and marsh plants including rice, taro, lotus, and water lilies. Subtropical house (opened 1964) – subtropical plants from the Americas, Africa, Asia, and Australia, including camellias, proteas, and tree ferns. Cactus house – cacti and succulents from the world's deserts and semi-deserts.

Photokina (rendered in the promoters' branding as "photokina") is a trade fair held in Europe for the photographic and imaging industries. It is the world's largest such trade fair. The first Photokina was held in Cologne, Germany, in 1950, and since 1966 it has been held biennially in September at the koelnmesse Trade Fair and Exhibition Centre in Deutz. The final Photokina under the then-current biennial cycle took place in 2018. Initially, the promoters planned to start a new annual cycle in 2019, with future shows to be held in May, but they later decided not to begin the new annual cycle until 2020. The worldwide outbreak of the Coronavirus disease 2019 and its effect on the imaging industry made koelnmesse decide to cancel both Photokina 2020 and Photokina 2021. Many photographic and imaging companies introduce and showcase state of the art imaging products at Photokina.
