The Tolshensky Spaso-Preobrazhensky women's monastery, located in the Voronezh region, is an Orthodox monastery founded in the first half of the 17th century. The monastery was closed in 1932 but was returned to the Church in 1994.

The history of the monastery begins in 1646, when the hermit Konstantin settled in a dense forest on the right bank of the Usmanka River, 40 kilometers from Voronezh. He lived in a tree hollow, fed on honey from wild bees, herbs, and roots, and wore clothing made from animal skins.

Tsar Alexei Mikhailovich allocated land to the monastery. Initially, the monastery was called the Konstantinov Desert in honor of its founder, and the nearby well also bore this name. After the construction of the wooden Spaso-Preobrazhensky church, the monastery became known as Spaso-Preobrazhensky, while the name "Tolshensky" is related to the thickness of the trees in the area.

In 1752, the construction of stone buildings began. First, a church in the name of the Merciful Savior with two chapels was laid, followed by a bell tower, stone fence, brotherly cells, refectory, and stable. The church was consecrated in 1759. The abbots were igumen and archimandrites, and the tsars supported the monastery financially. Income was generated from a mill and horse fairs.

In 1764, under Catherine II, the monastery became a non-staff institution, meaning it was left to its own resources. In 1768, Saint Tikhon (Sokolov), the Bishop of Voronezh and Yelets, chose the Tolshensky men's monastery as his place of residence but later moved to the Zadonsk Mother of God Monastery.

For some time, Father Gabriel, the brother of Metropolitan Eugene of Kiev (Bolkhovitino), was the abbot. Before its destruction, the monastery housed a wooden cross and the chair of the saint, as well as his portrait. In 1832, a chapel was built on the site of his cell.

Before the revolution, the monastery had two churches: a stone one built in 1884 and a domestic church. After the 1917 revolution, the monastery was devastated, and in 1932 it was closed. Books, icons, and church utensils were lost. The church was initially converted into a library, then a club, and the land was transferred to the Voronezh Nature Reserve.

The restoration of the monastery began in 1994. The territory was improved, the church was partially restored, the residential building was put in order, and a domestic church was arranged in the sisterhood building. In memory of the deceased brethren, a cross and a gravestone were erected.

Daily services are held in the church, and the monastery has a subsidiary farm. A Sunday school is open at the monastery, where children learn, help restore the monastery, and serve in the choir.
