London, Nov 10
A wall of ice melted in London Monday as part of celebrations to mark the 20th anniversary of the fall of the Berlin Wall.
The 3.5-metre-high art installation "Work in Progress" was erected outside the German embassy by German artist Benjamin Walther and his Welsh-born wife Manon.
With temperatures hovering around 10 Celsius, the wall immediately began to melt, changing in appearance as the day progressed.
The artists said the overall fleeting nature of the installation suggests that boundaries - both physical as well as mental and emotional ones - can be overcome.
The Berlin Wall fell Nov 9, 1989, paving the way for the fall of communism across Europe.
