During 40 years of Communism, no church schools existed in our country. After the Velvet revolution in 1989, the bishop of the Nitra diocese- Cardinal Jan Chryzostom Korec requested that a secondary school be established for boys and girls who wished to combine a university preparatory program with religious education.
The Gymnasium of Sts. Cyril and Methodius opened its doors in September 1991 as a four year school. In 1995, an eight year program was added and the school quickly grew to its present size of about 515 pupils.
A former monastery in the center of Nitra was returned to the Church reconstructed and modernized in recent years. At the beginning of 2005, the primary school of Sts. Svorad and Benedict was put under the administration of GCM and together they officially became the Combined Catholic School.
