When he returned to St. Petersburg in 1910, rehabilitated by the Tsar after a few years of exile in Paris, Grand Duke Paul asked Henry Delisle, with whom he had befriended him to draw and make the elements of decor of his new palace of Tsarkoe Selo. He manufactures all the chandeliers of the palace and, in particular, a Montgolfiere chandelier always of neoclassical spirit with patinated bronze vests that support cups carrying a few complementary candles.
