This beautiful building on Kurortny Avenue is known to many residents of Sochi as Villa Vera and is considered one of the first significant mansions in the city. The story began in 1872 when Nikolai Nikolaevich Mamontov acquired a large plot of land here. Soon, a wooden house was transported from Rostov, and a magnificent garden was laid out nearby. Under the guidance of foreign agronomists, palms, olives, yucca, magnolias, figs, eucalyptus, and almonds were planted in it. Over time, the garden grew to such an extent that local residents began to call it Mamontov Park.

In the early 20th century, Nikolai Nikolaevich's dacha passed to his relative Vera Kostareva. She decided to completely rebuild the wooden house, creating a solid estate. The work was overseen by her husband Nikolai Anatolyevich Kostarev, who was the city elder of Sochi. As a result, it became not just a mansion, but a real castle. Its elegance is manifested in noble strictness, proportions, volume grouping, and especially in the details of the facade, as well as in the unique patterns of window openings and latticework. Soon, Vera Kostareva's estate became one of the attractions of the resort city and was named Villa Vera.

After the October Revolution, the castle was nationalized. For some time, it housed the Council of Workers', Peasants', and Soldiers' Deputies of the Sochi District, that is, the local administration. It was in this building that Anton Denikin signed the act of surrender of the Volunteer Army on May 2, 1920, which became an important moment in the history of the Civil War. During the Soviet years, Kostareva's house was converted into a sanatorium, and during the Great Patriotic War, it housed an evacuation hospital. Later, the estate was transferred to the Palace of Pioneers and Schoolchildren. Since 1992, it has been operating as the Center for Extracurricular Work.
