Dějiny Prahy jsou spjaté i s jejím německým obyvatelstvem a jeho kulturou. SAMSA tě zavede na místa, jež nesou stopu této „německé Prahy“ – jsou spojená s činností německy mluvících architektů, výtvarných umělců, literátů, hudebníků, spolků, škol a dalších institucí. U každého místa appka nabízí německý text se základním popisem, informacemi k jeho dějinám a roli v kulturním životě, a několik současných i historických fotografií. Výklad stojí na ověřených zdrojích, ale nezahltí tě. Objevuj s mobilem v ruce pozapomenutou součást dějin města! Aplikace vznikla v rámci společného projektu Shromáždění německých spolků v ČR a studentů i učitelů germanistiky na Filozofické fakultě Univerzity Karlovy. Počet hesel bude průběžně rozšiřován.
