The reviews of this site are not very enthusiastic, but seem to stem from the fact that most people only visited the Georgium, which is the most central component and is located right across the street from the Bauhaus masters' houses in Dessau. I took a walk there as well, but since this is basically just a city park with some Baroque landscaping features added, I can understand why nobody was overwhelmed. The main part of this site, the Wörlitz Park, is much larger and provides a much nicer experience. It can be reached by a special train from Dessau (and a short walk from Wörlitz Train Station) and is a classic English-style landscape garden with many natural elements, large bodies of water, a few historic buildings, the expected birdlife from peacocks to swans, and, especially, a wide variety of bridges in different shapes, colours and sizes. On a nice day, it is a pleasure to take a stroll through the park (including several mini ferry rides). It still isn't a first-class WH site, but overall better than I expected.
