Martin Pošta made a mark on Prague in October when his Signal festival of light installations and video mapping brought an estimated quarter of a million people onto the streets over one weekend. The Croatian-born film school graduate – and former director of Fresh Film Fest – lives on Polská St. in Vinohrady, right by Riegrovy sady park. On a bench overlooking the park’s longest slope, Martin Pošta explains why he’s chosen this particular spot to begin our tour of “his Prague”.
