Miączyńscy family (Miączyńscy – Polish) is a notable noble family name
The family was related to Suchekomnaty coat of arms, dating back to the end of the XVI century.
The most prominent representative of the Miączyńscy family was Atanazy Miączyński (1639-1723).
He was a colonel of the Polish Army; Atanazy excelled during the liberation of Vienna
from the Turkish siege led by King Jan III Sobieski.
Emperor Leopold I granted Atanazy Miączyński the title of a Count of the Holy Roman Empire in 1683
In 1713 Miączyński was given the governorship over Volhynian Voivodeship  by a grateful King.
Prudent and far-sighted Miączyński, the owner of numerous lands, the governor,
amassed a multi-million fortune.

Atanazy Miączyński built a wonderful castle in his native town Matseyev that is in the Volyn.
This town belonged to Miączyńscy  family for over 200 years. Matseyev town became the main residence , with a castle in it.

At the end of the 18th century the great grandson of Athanasius – Franciszek Xavier Mionchinsky decided
to rebuild the half-destroyed old castle to a more comfortable and modern palace. The design was done by
Matthäus Daniel Pöppelmann – an architect from Dresden.
Next to the palace an English park was planted.
Starting from 1753 the family crypt in the rococo style was located there.
At present only ramparts, ditches and a stone bridge over the ditch remind about the former castle.

In Zawieprzyce, Lublin Voivodeship, Atanazy Miączyński  founded a hospital in his residence,
rebuilt in the Baroque style according to the plans of Tilman Gameren, for soldiers wounded in battle with the Turks and Tatars.

Atanazy Miączyński passed away in March 1723, he left a huge inheritance to his children, that consisted of 426 villages and 22 towns.
Miączyński’s fortune put them in line with the best families in the kingdom and helped to establish family
ties with the upper class of the Polish–Lithuanian Commonwealth.

Atanazy Miączyński enjoyed great authority and respect of local nobility that repeatedly
elected him as a representative of the Sejm.
Atanazy was honored with the sincere love of King Jan III Sobieski, and later of King Augustus II.

Atanazy Miączyński spared no money to support the construction of temples and monasteries.​
