Mikó Castle

It is named after Ferenc Mikó (1585–1635), who began building it a decade after becoming supreme captain of the Csíkszék (Ciuc), Gyergyószék (Gheorgheni) and Kászonszék (Caşin) Székely seats, later merged into Csík County.

After Ferenc Mikó's heirs died prematurely, the citadel came into the possession of Tamás Damokos, supreme judge of Csíkszék.

On 21 October 1661, Turkish and Tatar troops led by Ali, Ottoman pasha of Temeşvar Province, invaded Csíkszereda, occupying and burning the citadel.

For the rebuilt citadel, the Austrians designed a defensive system involving four Italian-style bastions, remnants of which are still visible on the south side.
