Two monoliths appeared in Poland in the same day. The one in Kielce is 2.5-3 meters tall, and the other is on the Vistula river. The Kielce monolith is made of steel, with a brushed brushed metal texture. It is currently unknown who placed the monolith.
On Friday, Dec 11 2020 it was examined by scientists from the Kielce University of Technology / Świętokrzyska Polytechnic. Professor Jerzy Piotrowski examined/analysed the monolith, and reported:
"It's a three-dimensional construction made from sheet steel, reinforced from within. The sheet steel appears to be of very good presentation [translator infers this to mean of high quality], it is sheet of 0.55 thickness. [Translator's note: units are not given, presumably either 0.55mm or 0.55cm.] It has good durability and hardness. By its appearance, I would judge it to resemble sheet steel that is usually manufactured for trade. As produced by a normal steelworks. It cannot be categorically established who manufactured it,"
