The Holocaust Museum has also recently banned Pokemon users from playing the game there as well.
"Allowing such games to be active on the site of Auschwitz Memorial is disrespectful to the memory of the victims of the German Nazi concentration and extermination camp on many levels", Pawel Sawicki said.
Although Niantic has yet to comment, Andrew Hollinger stressed out that they are, indeed, pro-technology with the use of social media, but using Holocaust Museum as "Pokemon Go" PokeStop is a different story. The Washington Post reported that the museum contains three different "PokéStops" - real-life sites where players can redeem in-game items.
The virtual reality game allows players to catch virtual creatures in a real-world semi virtual reality on their phones.
The museum at Auschwitz is not the only memorial landmark to host a game Pokespot.
Koffing also showed up by one of the pools at the 9/11 Memorial, right next to the names of first responders who died in the Twin Towers bombings, prompting a 61-year-old Staten Island laborer who helped clean up Ground Zero to say: "It's disrespectful to the people who lost families..."
The message, posted on 12 July appears to have subsequently removed.
"It's a place of peace and prayer and reflection and it's just not appropriate to play the Pokemon game there, so we're asking those Pokemon hunters to go elsewhere", Kunich said.
The United States Holocaust Memorial Museum and Arlington National Cemetery, both in the Washington, D.C. area, have both issued appeals for players to avoid hunting Pokemon on their sites.
The wild success of the online game - owned by Nintendo subsidiary the Pokemon Company and developed by studio Niantic Labs - had already seen the Japanese game-maker's stock price rocket by 59 percent in four days by Tuesday.
