Polesie National Park, Lubelskie Voivodeship
Polesia (Polesye) is a natural and historical region starting from the farthest edges of Central Europe and into Eastern Europe, stretching from parts of Eastern Poland, touching similarly named Podlasie, straddling the Belarus–Ukraine border and into western Russia.
The Polish part of the region includes the Polesie National Park (Poleski Park Narodowy), established 1990, which covers an area of 97.6 square kilometres (37.7 sq mi). This and a wider area adjoining it (up to the Ukrainian border) make up the UNESCO-designated West Polesie Biosphere Reserve, which borders a similar reserve (the Shatskiy Biosphere Reserve) on the Ukrainian side.
Smoleń, Silesian Voivodeship
Pilcza Castle was built in the mid-14th century as one of the Eagles’ Nests to provide protection of Polish-Silesian border.
The castle well was allegedly dug by Tartar prisoners.
Pilcza Castle was destroyed by the Swedish army in 1655. It has been in ruins since them.
Polish Aviation Museum in Krakow, Lesser Poland Voivodeship
The Polish Aviation Museum took over a few buildings and part of the grounds of the Rakowice-Czyżny airfield, one of the oldest military airfields in Europe.
The museum airfield was, at the end of the 1800s, home to a balloon detachment of Garrison Artillery 2nd Regiment of Krakow Fortress. Then, in 1912, the Austrian headquarters of the aviation unit called Flugpark 7 was formed there. During 1914, aircraft from Rakowice took part in the defence of Krakow Fortress and then, from 1915, as the war front moved on, the airfield was employed to train crews and repair aircraft for the front-line units.
The PZL TS-11 Iskra (‚Spark’) was the first domestically-developed jet aircraft to be produced by Poland and it has been used by the air forces of Poland and India.
