A building from the early 1920s, typical of the architects Kroha. You don't really know how to capture the school optically. It consists of different buildings, has different heights, window shapes. Rectangular forms dominate on the building and the windows and semicircles, such as the bars.
The intention was to represent a kind of machine, corresponding to the type of school. The architecture is a mix of a reduced Czech Cubism and a kind of constructivism, showing up new tendencies in architecture, such as flat roofs and and the use of concrete.
To underline the school as part of the Czechoslovakian State, the Bohemian lion as heraldic animal of the state, was placed above the entrance, a sculpture of the school's architect Jiří Kroha next to the entrance.
