Tiergarten has changed a lot over the years. The Potsdamer Straße, where our office is located, shows the controversies of this district. A few years ago, sex work and drug trafficking defined the neighbourhood. In recent years, many cafés, restaurants and galleries have settled here and helped to bring a more varied cultural offer to the area. With the Tiergarten park, the district also has the largest green area in Berlin, where thousands of people find rest from the hustle and bustle of the streets.
