Due to the progress in information and communication technologies urban space is more and more under the influence of its virtual representations existing in cyberspace. The concept of a digital shadow of the city is multidimensional and difficult to analyze. One of the methods is „cyberscape” – digital layers forming a palimpsest of the place. An analysis of two streams of social media data from Twitter and Flickr during four months of 2012 showed that Poznan’s cyberscape was highly dynamic during that time and strongly influenced by the Euro 2012 mega event. Additionally, it was possible to pinpoint relatively stable locations in the cyberscape that are probably a result of an underlying socio-spatial structure of the city.
