Warsaw's long-awaited second metro line opened on Sunday morning, with travel free for all on the inaugural day.
''This will change the whole of Warsaw – not just those districts which it passes through,'' Mayor of Warsaw Hanna Gronkiewicz-Waltz said on Sunday morning.
The new line, which runs from west to east, passes below the River Vistula, taking in seven stops. It complements the existing north to south line, which opened in 1995.
Construction on the new line began in mid-2011, and the walls of each station have been differentiated through the use of colour. Internationally acclaimed artist Wojciech Fangor was involved in the design.
Gronkiewicz-Waltz thanked Varsovians for their patience on Sunday, as the ultimate opening came after several delays.
