Petrovskoye-Alabino (Петровское-Алабино) is a ruined country house near the village of Alabino, in the Naro-Fominsky District of the Moscow Oblast. It is sited near the Desna River, about 50 kilometres (31 mi) southwest of Moscow, beside the route towards Kiev. The classical house was built in the late 18th century, probably designed by Matvey Kazakov, or perhaps his mentor Vasili Bazhenov, for the Demidov family. It has been described as "one of the most splendid of Moscow's country estates" and as one of the "most grandiose monuments" to the southwest of Moscow.
The land belonged to a monastery in the 17th century. It was acquired by Tsar Peter the Great and given to his vice-chancellor Peter Shafirov, who built a six-roomed wooden house, and also a church.
The property was acquired by members of the Demidov family in the 1740s, in the middle of the reign of Tsarina Catherine II. The Demidov family grew rich from iron founding in the Urals. Nikita Akinfiyevich Demidov, grandson of the blacksmith and gun manufacturer Nikita Demidov, decided to rebuild the house.
