In the 16th-17th centuries, large areas of North-Eastern Lithuania were ruled by the Biržai-Dubingiai branch of the Radziwiłł family.
[3] In 1748 Jan Ludwik Broël-Plater (1720-1764) and his wife Emerencja (c1730-177), the landowners of Dusetos-Antazavė, started building a manor designed by Laurynas Gucevičius.
An oval flower garden was installed on the main side of the palace facade, surrounded by a wide path, and two ponds were dug a little further and a bridge connecting them was built.
After Jan and Emerencja’s son, Count Ludwig Broël-Plater’s (c1740-1787) died, his wife Kunegunda (née Wollowicz) (1760-1847) built the church, rectory and hospital in Antazavė.
It was in Antazavė Manor that on 25 March 1831 Emilia Broël-Plater signed a statement announcing her decision to join the rebels in the November Uprising.
Ludwiga von Ropp, a descendant of Broël-Platers, was the first translator of the Brothers Grimm's fairy tales from German into Lithuanian.
[5] In 1915, the German occupying army established a commandant's office in the manor, collecting horses and dairy products from the residents.
In 1923, after the distribution of the land taken from the manor to volunteers and landless people, a new village-Šapalai appeared in the vicinity of Antazavė.
