The park was even more transformed when Pavlovsk became the imperial residence. Architect V.Brenna (1796-1801) expanded the palace. He built a large stone staircase, which connected the Palace district with Slavyanka, and also created a number of regular compositions: Big circles, Old and New Silvia.
During the work of the architect P. Gonzago (1801-1825) two new districts were created - the White Birch and the Parade Field, which occupied about half the area of the entire ensemble. They were located on a flat plain, in their structure there is neither a sculpture, nor architectural constructions, and in the area of the White birch there is no water spaces. The beauty and expressiveness of the appearance of these areas was achieved only due to the precise distribution of arrays, groups and individual trees and the skillful combination of their species. When constructing landscapes, P. Gonzago used the method of theatrical scenery, having plantings on the principle of their structure.
