The Children's House is a pavilion in the Alexandrovsky Park of Pushkin, built in 1830 by architect Gornostayev.

This small blue pavilion is located on an islet in the center of the Children's Pond, created in 1817 by architect Menelas. The house was built for the games of the children of Emperor Nicholas I. They reached the island by a small ferry, and later by a rowboat. The house contained a living room and four small rooms. Nearby was a small wooden kitchen. In front of the house stood a marble bust of Merder, the tutor of Alexander Nikolaevich, and to the right of the house was a marble bust of the poet Zhukovsky, who also participated in the upbringing of the heir to the Russian throne. In the second half of the 19th century, several beloved imperial dogs were buried on the island, their graves marked with small tombstones. Until the Great Patriotic War, the Children's House preserved children's furniture: in the room of Grand Duke Alexander Nikolaevich, upholstered in leather, and in the rooms of his sisters Maria, Olga, and Alexandra — in cretonne. Currently, the Children's House is under conservation.
