In pictures: Berlin's Festival of Lights transforms famous landmarks

The 17th annual Berlin Festival of Lights returned to the German capital earlier this month, shining a new light on the city.

The festival is known for its illumination of key landmarks throughout Berlin - including the Siegessäule, Reichstag, Brandenburg Gate, Berliner Dom, and many other sites around the city.

Organisers this year selected the theme: 'Creating Tomorrow', which saw artists highlight the environmental challenges facing the global population.

Artists turned the spotlight on concepts of sustainability, e-mobility, CO2 neutrality, renewable energies, and digitalisation.

This year attendees of the festival were treated to light shows, projections and video art at 70 different locations across the city.

The Festival of Lights is one of Berlin's most successful annual events, attracting over a million tourists every year.

For 10 nights Berlin's most iconic landmarks were brought to life in one of Europe's largest open-air art shows.
