Czechs to mark Earth Hour for second time

Czechs will join millions of people around the globe in turning off their lights for 60 minutes on Saturday night starting at 8:30pm local time in a symbolic show of support for the Earth Hour campaign against climate change. Earth Hour will dim some of Prague’s best known landmarks including Prague Castle, Charles Bridge, Petřín Tower, Powder Tower, Old Town Square or the Žižkov TV tower. Prague and other cities around the Czech Republic first marked Earth Hour in 2012. More than 150 countries participated in the event last year.
