The biggest feature of the palace built by a cardinal is the crystal palace, also known as the water palace, which is composed of various fountains, in the southern suburbs of Salzburg. Visiting the palace and gardens is free, but the Crystal Palace is charged with the group. It is recommended to pay attention to the tour guide's station and action when visiting, otherwise the wet body is inevitable. Fortunately, it is summer, and it doesn't matter if the strong sun is slightly wet. The fountains of the Halebrunn water palace are significantly different from those of the summer palace in St. Petersburg, Russia, the former are more secretive and more interesting, and the latter is more magnificent.
