In brief
Different styles are connected by a consciously shaped landscape.
Useful to know
Between the 17th and 20th centuries, rulers from Liechtenstein converted their lands to Southern Moravia. UNESCO describes a combination of Baroque, Classical and Neo-Gothic buildings with a landscape shaped by English romantic principles. [1]
Here the general design does not require one style for all structures. On a map, look for how the sites connect through the open territory. Then compare the individual building with the more distant view of it. Landscape architecture works with a sequence of views and spaces; the list of palaces alone does not show this connection.
