In the field of garden art, Isabela Lubomirska was known as the founder of one of the most famous Polish gardens named Mon Coteau. In her project the Princess worked with the leading architects and planners of those times, including Ephraim Schroeger and Szymon Bogumił Zug. Thanks to their cooperation a small, but very charming garden composition was created, which surrounded the Princess’ suburban residence. This article aims to present their work in Mokotów, considering mainly the works of Zygmunt Vogel, Alexander Majerski and Franciszek Kostrzewski. The iconographic material which they created has indeed great value, providing a range of information on the characteristics of one of the first Polish gardens established from scratch in the landscape style. The preservation of these documents and their in-depth analysis is of particular importance for the revaluation of the existing part of Mon Coteau.
