The long single-story house No. 9, painted yellow and currently occupied by the Embassy of Denmark, was one of the most famous literary and artistic salons in Moscow and an intellectual center of the city in the early 20th century. It was founded by Margarita Kirillovna Morozova, the widow of a prominent Moscow merchant, Mikhail Abramovich Morozov. In 1910, she purchased this mansion, selling her large house on Smolensky Boulevard and donating 60 paintings from her husband's collection to the Tretyakov Gallery.

The right part of the building is an Empire-style mansion, built by Captain N.I. Voeykov by 1820, and later passed to Major Guryev. In 1905, Guryev's descendants slightly altered the interior and added a grand vestibule. To furnish the mansion to her taste, Margarita Morozova invited the young architect Ivan Vladislavovich Zholtovsky. In 1913, he added a large annex on the left in the neoclassical style, which included a hall and a large reception room with access to the garden through a terrace.

Zholtovsky organized the space width-wise, between the windows on the street side and large glass openings of the balcony overlooking the garden. The large reception room was designed to let in a lot of light, with sunlight illuminating it at any time of day. Visitors to Morozova's salon noted that the mansion was a model of good taste. The hall contained paintings that Morozova kept for herself: works by Serov, Vrubel, and Korovin. The elongated dining room, furnished with furniture made of Karelian birch, was decorated with antique icons and paintings by famous masters. The living room was adorned with Vrubel's painting "Faust and Margarita in the Garden," Empire-style bronze items, and numerous flowers. All of this created a special atmosphere of beauty, spirituality, and well-being during Morozova's evenings, where up to a hundred people gathered. The mansion hosted renowned philosophers, musicians, and scholars who formed the Religious-Philosophical Society named after Vladimir Solovyov. The works of the society's members were published by the "Path" publishing house, established with funds from Margarita Morozova in 1910.

In 1918, the mansion was nationalized, leaving the owner a room in the basement, while the building housed the Department of the People's Commissariat for Education for Museums and the Protection of Monuments, led by Trotsky's wife, N.I. Sedova. Many well-known cultural figures worked here, and Igor Grabar headed the sub-department of the National Museum Fund. In the 1920s and 30s, it housed the diplomatic mission of Norway, and in 1945-1946, that of Yugoslavia. Since 1946, the house has belonged to the Embassy of the Kingdom of Denmark, which occupies it to this day.
