A German artist has travelled the world fixing broken walls and monuments - with Lego.

Jan Vormann, 26, an artist from Berlin - who estimates he's used thousands of the toy building bricks - has spent the past three years fixing crumbling buildings.

Mr. Vormann enlists the help of intrigued passers-by and claims he has brightened up thousands of people's lives with the brightly coloured bricks.

He said: "My work draws attention to the smallest parts of our cities that are falling apart because of the brightness of the Lego. It draws people's attention through the coloured blocks and makes them aware that this wall or statue or construction is not complete anymore, for whatever reason."
