Damerau (Old Prussian) (until 1938) Dombrowken (1938-1945) Eibenburg.
The first traces of settlement in the Węgorapa valley come from the 10th century.
The name Damerau comes from the Old Prussian Damerouwe – oak tree; oak forest.
The Dombrowken property has existed since the 16th century. It belonged to Count Schlieben-Dombrowken, a descendant of the Schlieben family from Birkenfeld. Then the property passed into the possession of the Thiesel von Daltitz family. Subsequently, Adolf Friedrich von Langermann († 1757) and Karl August von Hohenstock († 1788) became owners of the Domobrowken manor.
Around 1790, war counselor Friedrich Wilhelm Johann von Fahrenheid (1747-1834) bought numerous property complexes in the area, including Dombrowken. It is worth mentioning here that he was the builder of the Pyramid (tomb) in nearby Rapa. Then the property went to Emilia Fahrenheid, his daughter as a dowry at the marriage of doctor Ferdinand Voigdt from Królewiec.
One of the largest private studs in East Prussia has developed in Dombrowken, with a herd of 30 English thoroughbred mares, the so-called Folbluts.
The neoclassical manor house from 1862 has survived to this day in ruins with a clear population of trees in the manor park with an area of approx. 5 ha. From 1818, Dombrowken belonged to the newly created County of Darkehmen (Angerapp County since 1938, Angerapp County since 1938) in the Gumbinnen County of the Prussian Province of East Prussia. On July 16, 1938, Dombrowken was given a freely invented, Germanized name of the town of Eibenburg. The Polish name of the place is a diminutive form of the word Dąbrowa, which in translation means an oak forest. Some southern towns of the poviat have been assigned to Polish communes, incl. Dombrowken, which received the Polish name of Dąbrówka. In order to distinguish it from many other Polish towns called Dąbrówka, the names Dąbrówka Litewska and Dąbrówka Nowa were also used in the past.
In view of the incompletely established border, after World War II, Dąbrówka passed over to the Russian side several times and returned to Poland.
In the first post-war years, mainly displaced Poles from Lithuania and Ukraine were settled here. In 1948, school teaching resumed. The property with the palace became the property of the State Agricultural Farm (PGR).
