In a room at the Secondary Grammar School on Varšavská Street in Žilina, a group of 11 teenagers are talking about the 1989 Velvet Revolution which brought down the communist regime in then Czechoslovakia.
The students, all aged between 16 and 18, recently took part in a project talking to people who lived through the revolution and the communist regime that preceded it - often someone imprisoned or oppressed for their opinions, religion or political beliefs - and recording their stories.
Organised by the Nenápadní Hrdinovia (Inconspicuous Heroes) civic association, the project has helped students like Miriam Bandíková gain a greater understanding of one of the pivotal events in Slovak history.
