Entry to the rooms is from the Grand Staircase which dates from the 1840s and is by the architect Nikolai Efimov, who is responsible for several landmark buildings in St. Petersburg. Later a graceful decorative stucco dome was added over the staircase by architect Rudolph Bogdanovich Berngard. He was also responsible for the 19th century reconstruction of the embankments of the Fontanka River, so his influence can be seen both inside and outside the palace.
The palace's Red Room is dedicated to Russian silver works, produced from the 18th to the early 20th centuries. The room showcases spectacular works by Carl Fabergé and Pavel Sazikov, among others. The Anteroom holds a collection of household items, such as clocks, in guilloché enamel, as well as Fabergé jewellery, which is quite rare. The White and Blue Room displays works in enamel from Pavel Ovchinnikov, who was also the first Russian silver maker in the pan-Slavic revival style, along with excellent Russian porcelain from the 19th century. The Exhibition Room exhibits stone carvings by Fabergé and various nineteenth century Russian artists.
