The village of Devletyakovo, located in the Voznesensky district, is known for its architectural and urban planning monument, a church dating back to the late 18th century. According to the document on state protection No. 471 and information from local historian Vladimir Bakunin, the church was built in 1789. It houses the main cold altar of the Holy Trinity and a warm chapel of Zacharias and Elizabeth. A unique feature of the bell tower is its rare perfectly round shape. Nearby, one can see the ruins of a wooden noble house from the estate that belonged to Yengalychev. According to information provided by E.A. Sorokoumova Ilyinskaya, the estate in Devletyakovo was owned by Prince Andrei Nikolaevich Yengalychev. His daughter, Princess Anna Andreyevna Zvenigorodskaya, lived in her husband's estate in the village of Kotovka in the Ardatov district of Nizhny Novgorod province after her marriage.
