A committee led by Emil Lochner, an Aachen textile factory owner, bought the green spaces in front of the Junkerstor in 1882. In the year 1885 the Lochnergarten was formed And formed the substitute for the splendid English garden at the Lochnervilla between Lochnerstrasse and Karlsgraben. In the same year, the zoological garden Aachen was opened under the leadership of the textile manufacturer Lochner, which housed about 50 giant snakes, bears and tigers as well as numerous domestic animal species.
The park was financed partly by shares. In 1882 a glass palace was built next to the park with a large, round hall with many annexed rooms, the walls of which were made of glass. This palace accommodated up to 3,000 visitors.
