Danger of collapse at Gjirokastra, Albania's slanted city The fortified centuries-old houses of Gjirokastra, that earned the Albanian city the prestigious UNESCO World Heritage site designation in 2005, are endangered.

Citizens, authorities and NGOs are fighting to preserve this world heritage jewel. IMAGES AND SOUNDBITES
