Via Facebook, the dates and locations for the Unibail-Rodamco events have been announced by Niantic. For those who are unfamiliar, Unibail-Rodamco is a shopping mall company in Europe that has partnered with Niantic to have loads of PokéStops placed throughout them. The malls will be lured all day during the event and will have an opportunity for Trainers to get their picture taken with Pikachu.
