The Olgin Pavilion is a gift from Emperor Nicholas I to his daughter, Grand Duchess Olga Nikolaevna, on the occasion of her marriage to Prince Karl of Württemberg. The pavilion is built in the style of country villas of the island of Sicily, whose capital, Palermo, was where the marriage of the Grand Duchess was decided. The Olgin Pavilion was constructed between 1846 and 1848, designed by architect Andrey Ivanovich Stakenschneider.

Colonists' Park is a 29-hectare landscape park in Peterhof. Colonists' Park was created based on a design by architect A. I. Stackenschneider during the reign of Nicholas I. A special role in the creation of the park was played by the chief gardener of the Peterhof Palace Administration, P. I. Erler. The boundaries of Colonists' Park are: to the south — Erler Boulevard, to the east — Borodacheva Street, to the north — the embankment of Olgin Pond, and to the west — Samsonievsky Pond-Canal.

The Tsaritsyn Pavilion was built by architect Stakenschneider in 1842-1844 for Empress Alexandra Feodorovna during the landscaping of the area south of the Upper Garden. The first of these was designed by the architect in the then-fashionable "Pompeian style." It was meant to reproduce the appearance of ancient Roman houses uncovered during the excavations of Pompeii. Unlike the buildings of the previous century, it introduced a "romantic note into the architectural symphony of Peterhof." Alexandra Feodorovna loved to rest here from the exhausting palace ceremonies.
