As the oldest secondary school in Inland Dalmatia, work began in 1838/39, after monastic schools in the three monasteries of the Franciscan Province of the Most Holy Redeemer had been joined. Through the 1854 reorganisation it acquired the right of public work. The Sinj Franciscan Grammar School is also the first secondary school in southern Croatia which introduced the Croatian language as a language of instruction. The Alka Knights Court (Kvartiri) is cultural property under the protection of the Ministry of Culture of the Republic of Croatia.
