The renaissance castle of its builder Hídvégi Mikó Ferenc, has been ravaged and raided by Turkish-Tatar troops in 1661, the ruined edifice being transformed into a fortified barrack by the newly installed Habsburg power by the year 1716. Until 1970 it has been serving military purposes, and then became the home of the Szekler Museum of Ciuc. The story of four centuries is caught out here, since the tracks of successive events have constantly piled up, keeping slumbering witnesses of earlier times. Going back from the present through scientific researches, the historical past gradually unfolds before our eyes.
