Grobisko ariańskie w Krynicy, Pyramid tomb in Krynica, Poland.

Grobisko ariańskie w Krynicy is a stone pyramid structure in the village of Krynica measuring 20 meters high with walls 80 centimeters thick made of stone and brick. The square base spans 7.35 meters and encloses a crypt beneath its peak.

Paweł Orzechowski, chamberlain of Chełm and an Arian, built this pyramid tomb probably in the first half of the 17th century because as an Arian he could not be buried in a Catholic cemetery. He died on 21 March 1612 and was likely interred here. Damaged in World War II, the structure was restored in 1956–1957.

The tomb is linked to Paweł Orzechowski, a member of the Polish Brethren (Arians), who could not be buried in a Catholic cemetery. Oskar Kolberg recorded in 1890 a local belief that treasures were hidden inside the structure. The site lies on the yellow Arian Trail, and the original pyramid top is kept at the Regional Museum in Krasnystaw.

The tomb stands on Arianska Hill, a limestone rise 290 m above sea level, about halfway between Krasnystaw and Rejowiec, west of regional road 812 and just north of Krupe. It is a stop on the yellow Arianski Trail. The structure is not visible from the road to Rejowiec; the hill was bare in the 1960s but is now covered with young pine forest.

The original top section of the pyramid was removed and is now displayed at Krasnystaw Regional Museum, leaving the structure modified at its peak. This separation preserves both the monument itself and a key element of its original design.
