The castle was built in the middle of the 16th century by craftsmen from Sweden, who were invited and paid by Duke Matas Giedraitis and his son Martynas Giedraitis. The castle, called Mūriniai Videniškai, entered the defence system of the middle part of Lithuania and protected the old Vilnius-Riga road. In the 17th century, an ornate manor palace was built, and a renaissance garden was established. The palace contained the so-called golden hall and treasury. Baltadvaris Castle is a unique example of military wood and stone architecture, which combines two styles and technologies - Lithuanian and Swedish.
