Siekierki
The earliest known settlement in the present-day Siekierki area, formerly known as Kępa Bełt, was the village of Czarnów, known since the 13th century and situated along the Wilanówka River, which then flowed into the Vistula.The entire village was an integral part of a local manor's agricultural estate (folwark), which in 1884 covered an area of 556 morgen (equivalent to 3.11 km2 or 1.2 sq mi), mostly consisting of meadows and pastures.[4] The village of Siekierki, belonging to the Wilanów gmina at the time, was incorporated into the city of Warsaw on April 8, 1916 by a decree of Hans von Beseler, along with the rest of Mokotów.[3][7] During the Warsaw Uprising the neighbourhood suffered from tragic reprisals against the Polish population as the Nazis carried out mass murders and arsons resulting in majority of buildings being destroyed, including the local manor.[12] Despite the mentioned unrealized investment plans over the years Siekierki remained an underdeveloped and largely unused area; however, the early 2010s marked the onset of a substantial increase in new residential housing developments.
