A comprehensive educational institution for students in the first to eleventh grades. The institution acquired its modern appearance in 1883. It was then that German schools were built in all medium-sized and large cities of Galicia from red, unplastered brick in an arcaded, neo-Gothic style, which is characterized by high Gothic pediments. The architect of the building was Lviv architect and teacher Tadeusz Vaclav Münnich, as indicated by the school project plan.
The six-grade Public School in Kalush contained a female and male department. The main facade is symmetrical. The entrances to both schools were located in the center of the building. The set of premises for each department consisted of eight classrooms (one classroom for 40 students and one for 60; two classrooms for 50 and three for 80 students); a "religion" classroom; offices and bathrooms on both floors in each wing.
Part of the first floor in the flank parts of the courtyard facade was allocated for the residence of the leaders. In the right, female part of the building, there is a two-room, in the left – a three-room apartment for the head of the male department and, part-time, the director of the entire school.
In 1920–1939, an elite Polish gymnasium operated here. It began to function as a Ukrainian school in 1939. Since 1976, a comprehensive educational institution has been operating here. Since September 1992, the school has owned the entire building.
In the basement of the building there is a Museum of Antiquities, created by the teacher of musical art and culture Mykhailo Hnizdovsky on March 29, 2011.
