The first grammar school in Mariánské Lázně was German – Real Gymnasium. At that time, the Czech population was in the minority and did not have its own secondary school. The German grammar school was founded in 1920 and first operated as a branch of the grammar school in Karlovy Vary. This meant that it was taught in Mar. Students had to pass the spa, but the final exams in Karlovy Vary, and they also received a certificate there. It was taught in three houses in Lesní street. From 1925, the town of Mariánské Lázně took over the grammar school and moved it to a new building in Komenského Street, today’s seat of the Hotel School.

Since 1931, the school has been an independent city real grammar school with all the rights, ie the right to take entrance and final exams and issue certificates. It was taught in German. The director of this grammar school was Professor Franz Görgl from Úšovice until 1942 and after him Professor Karl Eigermann until 1945. In the period 1938 – 1945 the school was taken over by the state administration.

The Czech Grammar School in Mariánské Lázně also has a rich history. It was founded in 1945 by a decree of the Ministry of Education and Enlightenment on September 6, 1945, so in 1995 we celebrated its 50th anniversary. To this day, there are teachers who started here at the time, and they remember the zeal with which they built the Czech state real grammar school in a traditionally German environment. The school was located in the building of the former German real grammar school, where the Hotel School is located today. The first director was Eduard Černý, who had previously worked as a professor of Czech and Latin at the grammar school in České Budějovice. The faculty had 14 members and the first school year was attended by 113 students. During the year, the number of students increased to 131. Interestingly, the school also included a dormitory in Třebízská Street, today’s Windsor Pension.

In the first school year, the grammar school had only 7 classes, the first year was not opened. In the next school year 1946/47, the grammar school already had 8 full classes and 149 pupils. Since this school year, the school has been located in the current building at 355 Ruská Street. professors and expulsion of students) and the grammar school was relocated to nearby Planá. Formally, this decision was justified by the “optimization of the secondary school network”. Director E. Černý also left for Planá and V. Pospíšil was commissioned to work on the liquidation of the school. The exile lasted 11 years, only in 1960 did it return to Mariánské Lázně and start teaching as an eleven-year high school. The school was located in a building in Úšovice.

Three years later, the school was changed to the Secondary General Education School (SVVŠ). From 1962 until 1969, the director was Miloslav Pelc, who strengthened the position of the school in the town and belonged to important personalities of the town of Mariánské Lázně. After his departure, J. Korbelář became the director, with whose name the renaming of the school to the grammar school is finally connected, but also the personnel examinations after 1970, which the whole company went through at that time.

In 1972, the grammar school moved again to its original building at 355 Ruská Street, where it has been operating together with the 2nd Sever Primary School ever since. From 1973, A. Horáčková was the director, who contributed to the calming of the teaching staff after inspections and the general consolidation of the school. She became the longest-serving director of the grammar school for 12 years, until 1985, when J. Matoušek became the director. During his work, there were also many changes. Multiannual studies were started (first seven years, later eight years), but at the same time four years of study were abandoned, which, as it turned out, was a mistake. The principal had the idea that the school would function as an eight-year grammar school with two classes per year, for a total of 16 classes. This idea never came true. The grammar school had the most students in the 1993/94 school year, 426 students in 14 classes. Then the decline in four-year study began and the number of classes and students began to decline. The lowest occupancy of the school was in the school year 1998/99, when the grammar school had only 11 classes and 321 students.

Since 1994, J. Smazal has been the director. In addition to seeking to raise more funding for the school by establishing the Grammar School Foundation and investing in the school’s material equipment (televisions and videos, new computer room, new seminar room, new cabinets), it seeks to return four years of study, which should be parallel to eight years. After a futile attempt in 1998, this was not achieved until the school year 1999/2000, when a new first year of four-year study was opened, despite the fact that, in general, there is more of a reduction in education. The goal of the current management is a grammar school with at least 12 classes, 8 in an eight-year cycle and 4 in a four-year cycle. This combines tradition with the need of the present for general secondary education in our region.
