The image shows a narrow, dark tunnel made of white brick. It appears to be a passageway through a stone wall. A sign above the entrance is inscribed with the words "GROTA JÓZEFA PIŁSUDSKIEGO POCZĄTEK XIX W. THE JÓZEF PIŁSUDSKI GROTTO BEGINNING OF 19TH CENTURY" in English and Polish. The tunnel itself is mostly dark except for a band of green light in the middle, which is reflected in a pool of water at the bottom. There are small, dimly lit lanterns lining the sides of the tunnel. At the very bottom of the image, a wooden fence and another sign with the text "CROLLO BOCSVLEK XIX M" in Polish are visible. This image depicts a tunnel entrance with a reflective pool of water and green light.
