Pregolsky Microdistrict

Prior to World War II, it was known by its German language name Holstein (archaic Hollstein[1]) as first a suburban estate and then a quarter of Königsberg, Germany, located west of the city center.

Located 7 kilometers (4.3 mi) from medieval Königsberg on the northern shore of the Pregel near where the river flowed into the Vistula Lagoon,[2] the Old Prussian village of Kasewalx was first documented in 1405.

From 1693 to 1697, Frederick tasked Georg Heinrich Kranichfeld with building the hunting palace Friedrichshof near the Langerfeldkrug inn according to a design by Johann Arnold Nering.

[6] It was one of the finest examples of Baroque architecture in East Prussia, with high arched windows reminiscent of Charlottenburg Palace.

The city became Russian Kaliningrad after World War II; Holstein was renamed Pregolskiy after the Pregolya (Pregel) River.
