We begin our exploration from one of the most controversial places in Warsaw - the Abandoned Estate on Dudziarska Street. This is a place that until recently was teeming with life, but today stands empty, a reminder of a failed social experiment.

Location: Dudziarska 01 Estate, 04-317 Warsaw. How to get there: The nearest bus stop is 'Olszynka Grochowska', from where you need to walk about 500 meters.

The estate was built in 1993-1995 as an attempt to create a place for people evicted from other parts of the city. Unfortunately, it quickly became known as 'the worst address in Warsaw.' Its location between railroad lines, adjacent to a detention center and a garbage incinerator, was not conducive to social integration.

Today, the estate is completely abandoned. The entrances to the buildings are walled off, and the area is monitored. Nevertheless, the place attracts urban explorers from all over Poland. Remember, however, that it is officially forbidden to enter the estate.

What you can see:

• Three abandoned apartment blocks
• Remnants of the estate's infrastructure
• Graffiti and traces of vandalism

Security:

• The area is monitored, possible security interventions
• Buildings may be unstable, use extreme caution
• Do not go inside the buildings - it is dangerous and illegal

Nearby:

• Jozef Polinski Park - an ideal place to rest after exploration
• Warszawa Wileńska Shopping Center - if you need to replenish your supplies

The abandoned Estate on Dudziarska Street is a place that makes us reflect on social and urban problems. Although we can't go inside, just being there and observing from the outside can be a fascinating experience for urbex enthusiasts.

The next point on our trip is the Temler and Szwede Tannery Factory, a witness to Warsaw's industrial history. This is a place that for decades was the heart of Warsaw's tanning industry, and today stands abandoned, waiting for a new purpose.

The factory was founded in 1823 and for almost two centuries was one of the most important industrial plants in Warsaw. It survived two world wars and finally ceased operations in the 1990s.

• The buildings are in various states of preservation, some partially ruined

How to visit:

• It is worth coming at different times of the day - at sunset the buildings look especially picturesque

The Temler and Szwede Tannery Factory is a fascinating site for lovers of industrial heritage. Although we can't go inside, just being there allows you to feel the spirit of Warsaw's industrial history. Remember that the future of this facility is uncertain - it may soon be adapted to new functions, so it's worth seeing it while it still retains its original character.
