The European Central Bank (ECB) allows graffiti artists to use the fence around the construction site of its new headquarters in Frankfurt as a public gallery.

The works are often politically charged and deeply critical of German Chancellor Angela Merkel, ECB President Mario Draghi and capitalism in general.

Construction of the new building started in 2008 and is expected to be completed later this year. IBTimesUK presents a gallery of some of the murals that have adorned the hoarding over the last few years.
