17 Słowiańska Street in Kwidzyn, Historical school building and heritage monument in Kwidzyn, Poland.

17 Słowiańska Street in Kwidzyn is a school building featuring neoclassical design elements from the 19th century. The symmetrical layout, large windows, and robust facade are characteristic of educational institutions from that period.

A cathedral school existed here by the 14th century, teaching clergy for Pomesania; it declined after the Reformation and the dissolution of the cathedral chapter in 1527. In 1802 the Marienwerder government resolved to turn the town school into a Gelehrtenschule, and in 1813 it received the name Gymnasium, becoming a Royal Gymnasium three years later. Its motto was PIETATI LITTERIS VIRTUTI.

The school's motto was PIETATI LITTERIS VIRTUTI, and lessons centred on ancient languages, religion and history. Until 1836 every rector was a theologian, and candidates for the post were examined in theology, logic, geometry, physics, arithmetic, history, Hebrew and Latin. A Polish chaplain also taught at the town school.

The building remains an active school and is viewable from the street, allowing visitors to admire its architecture from outside. Its central location on Słowiańska Street makes it easily accessible and well integrated into the town center.

The school's motto was PIETATI LITTERIS VIRTUTI, and from 1813 it carried the name Gymnasium, three years later Königliches Gymnasium. Its medieval predecessor, the Domschule, was probably founded between 1285 and 1323 and peaked around 1400; 23 of its pupils appear in university registers between 1400 and 1525.
