The definition of the ubiquitous in art idea of sacrum is always quite subjective. That’s why it should be always viewed through the prism of an individual and cultural themes that guided and shaped the author or the founder of a particular piece of art. Natural and scenic wealth of Silesia with the cultural background and the garden design dated back to the 19th century, is an excellent example of pluralism of sacrum, which in the area of a garden can be marked by a path, sculpture that is a symbol of the national power, by a garden itself as a gift and by the landscape in general.

The authenticity of the historical garden, as defined by the Florence Charter, is conducive to its broad interpretation. In the era of the present crisis of conservation values, the identification of criteria helpful in an objective assessment of the authenticity of both historical and historising forms of greenery is required.

On the example of the restoration’s solutions in the gardens at Wilanów and the condition of selected elements of the urban greenery in Warsaw, it is possible to verify the model of valorization of factors determining the vegetation’s authenticity proposed by the author of the article. This model also allows to emphasize the features determining the role of royal gardens in Wilanów in maintaining the historical horticultural values of modern Warsaw.
