Around 1622, the Benedictine nuns in Vilnius accepted female students. This was part of the general trend of establishing schools, and was also due to the shortcomings of the monastery, which needed income-generating activities. When, thanks to the dowries of the magnate's two daughters (1700), the order's endowment increased, over the next century its school activities periodically ceased and were resumed. Under the influence of Enlightenment ideas, on the orders of the bishop (1792), a school was established for poor girls, who were taught at the expense of the monastery, and a boarding school for wealthy girls. Several nuns worked as teachers, governesses who took permanent care of the girls and teachers from outside the monastery were paid. The sources allow us to precisely trace the rapid development of the school program: the introduction of new courses and the extension of teaching hours in the years 1805-1827. The school was closed by the Russian government in 1843.
