In Košice, the metropolis of Eastern Slovakia, the theatre has more than six hundred years of tradition. The theatre was performed in diverse places: in the open air, on the provisional stages of wooden shanties, in schools, as well as in various buildings. The current building of the State Theatre of Košice whose name changed many times during its history up to now, is a historical building. It belongs to the distinguished cultural monuments of the City; moreover, it is an important dominant of the historical core of Košice City. The building dating from 1899, the work of the architect Adolf Lang (history labels him to be one of the most gifted architects of 19th century in Europe), ranks as one of the most beautiful theatre buildings in Europe.

The State Theatre of Košice was established in 1945 under the name East-Slovakian National Theatre (later on, its name changed many times, similarly to other Slovak theatres). When founding the new theatre, its foundation director Janko Borodáč followed the structure of the Slovak National Theatre of Bratislava. He therefore banked on integrity of the artistic work of three ensembles: drama, opera/operetta, and ballet. At the beginning, he failed to create the latter. For the long two years the ballet was just a “service body”

The drama ensemble of Košice theatre entered into the context of the Slovak stagecraft with the premiere of the play Marína Havranová (on 15 September 1945). At almost the same time, also the team of opera ensemble introduced with the premiere of the operetta Polish Blood (on 6 October 1945). The first ballet evening in Košice was in 1947: on the programme there were the ballets Les Sylphides, The Little Mermaid, and The Polovec Dances.

The artistic development of Košice State Theatre drama has so far been mostly influenced by the stage director Janko Borodáč. In Košice, he stage-managed 24 plays, a half of them were titles from Slovak and Russian classics. The Borodáč´s systematic formation of the ensemble in the spirit of realistic methods of stage-managing left an everlasting track on the histrionic work of its members. And the stage-managers, who were operating in Košice for a long time after Borodač´s departure, were also his direct pupils or grew under his pedagogical and artistic influence. At present, after a period of a kind of consolidation after previous restructurings that has reflected on the troupe, dramaturgical choice and the quality of productions, the drama is being revived. The art chief has even two stages for that purpose: in addition to the main stage in the historical building of the theatre also a small stage in the former studio Smer (Direction).

Nowadays, the largest body of the Theatre is the opera ensemble. For the period of its 60- years´ existence the body performed a number of opuses from the worldwide, Slovak and Czech opera literatures. Of the singers who were performing in the State Theatre of Košice, and rose to become soloists of international significance we can mention here the names such as Sergey Kopčák, Štefan Margita, and Ida Kirilová. The opera ensemble has the works like Carmen or The Barber of Seville in its repertoire. Moreover, on the regular basis, the body also introduces the operetta works and the works for children (The Puss in Boots, The Merry Widow).

The Ballet of Košice State Theatre is one of two Slovak professional bodies that perform classical ballet literature. At present, the ensemble has titles for all the age categories of audience in its repertoire, from fairytales to modern dance works (The Little Prince, Bolero, Carmen, The Badly Watched Girl).
