Siejnik (formerly Elisenhöhe) is a rural farm, now a suburb of Olecko, located on the right side of the Olecko-Luk road. An avenue of linden trees planted almost 15 years ago leads to it. Currently, a new settlement has formed around the manor. The estate belonged to Gottfried Zimmermann (1770-1858) and his third wife Elise Zimmermann (1788-1874). Both of them were the owners of the Lenz Hotel, which was established near the main square of the city, and other buildings in the city. Elise Zimmermann has established herself in the history of Marggrabowa forever. Her friendship with the Prussian ruler Frederick Wilhelm IV of Hohenzollern actually contributed to this to a large extent. Between 1838 and 1856, many letters were sent between Marggrabowa and Berlin by the town’s resident and the king. Her face is immortalized in H. Friedrich’s painting from 1853, which depicts the ruler’s arrival in Marggrabowa in 1845. Frederick Wilhelm IV, sitting in an open carriage, is greeted by a large crowd of residents in the flower-festooned main square of the city. On the right side, at one of the brick houses, you can see a woman in a dark dress and hat – the owner of the Elisenhöhe estate. Many anecdotes and stories have been created about Elise Zimmermann, and she was given the nickname “Madamchen”, which means “Lady” in German. Die-hard city history enthusiasts associate it with Arthur Zimmermann (born in 1864 in Marggrabowa – died in 1940 in Berlin), who became famous for adventures completely uncharacteristic of people occupying serious state positions. He, as the foreign minister of the German Empire, sent a telegram to the imperial embassy in Mexico in January 1917. The provocative content of the telegram led the hitherto neutral United States to enter World War I.
