Not only has the Russian government refused to grant permission for a permanent monument dedicated to Nemtsov at the site, there have in the past been multiple attempts by the authorities and sometimes even by nationalist and pro-government vigilantes to destroy the makeshift memorial that has sprung up on the Bolshoy Moskvoretsky Bridge instead. As a result of these once frequent actions, a group of volunteers has worked for years now to guard the monument on what is known universally as Nemtsov Bridge.
