The Late Gothic palace was built in about 1490 as the seat for the administrator of the Boleslav demesne. The three-storey building is a gem of the Late Gothic architecture from the Jagiellonian Period.
Until the Battle of White Mountain, it had been owned by significant noblemen, then it was sold as a seized property and became the property of the leading burghers in Mladá Boleslav. During the Thirty Years War it was affected by fire. Extensive adaptations in the Baroque style followed. In 1886 - 1910, the Regional Museum had its seat there. In the 1920s, the temple served as a prayer room of the Czechoslovak Hussite Church.
Today, it serves as an exhibition hall; literary/musical programmes are organised here. In June 2000, TEMPLUM HISTORICUM ET ARCHEOLOGICUM BOLÉSLAVIENSE, a permanent multimedia regional museum exposition, was opened here on the initiative of the municipality.
