Liceum Hosianum, Jesuit Collegium, Braniewo

In 1296, a Franciscan monastery was founded in Branievo, which changed its location three times, and in 1330 finally settled in the North-Western corner of the inner defensive wall of the city. Here the monks built residential and commercial buildings, a Church, as well as a tower named Klesza, which became part of the city's fortifications and has been preserved to this day. The monastery buildings were demolished in 1749, the Church in 1809.

In 1565, Bishop Stanisław Hozjusz of Warmia transferred the monastery to the Jesuit order and founded a gymnasium at the monastery, the first educational institution in the Polish lands that trains clergy. Initially, there were about 20 students, in addition to theology, mathematics, dialectics, German and singing were also taught here. By the end of the 17th century, students in the College studied philosophy, theology, mathematics, Greek and Hebrew. By that time, the College was already widely known outside However, many foreigners studied here, and in 1701 the College received the status of a University. In 1743, a new academic building was built, where about 300 students were trained.

In 1780, after the dissolution of the Jesuit order in 1780, the College was transformed by the Prussian authorities into the Gymnasium Academikum. During the Second world war, the building was severely damaged, and in 1964 a secondary vocational school was opened here. Over time, new academic buildings were built for the school, and in 2016, the Branievo Land Museum (Muzeum Ziemi Braniewskiej) was opened in the premises of the old college and the Klesza tower.
