After World War II Wedding was part of the French Sector. Wedding was the western terminus of one of the first refugee tunnels dug underneath the Berlin Wall. It extended from the basement of an abandoned factory on Schönholzer Straße in the Soviet sector underneath Bernauer Straße to another building in the west. Though marvellously well constructed and its secrecy maintained, the tunnel was plagued by water from leaking pipes, and had to be shut down after only a few days of operation.

A section of the Berlin Wall has been reconstructed near the spot on Bernauer Straße where the tunnel ended. Two sections of wall run parallel to one another down the street with a strip of no man's land in the middle. A nearby museum documents the history of the Wall.

Today, Wedding is one of the poorest areas of Berlin, with a high unemployment rate (almost 26%). Almost 17% of the population live on social welfare; 27% live below the poverty line. Foreigners make up almost 30% of the population. Low rents accompany the poverty in Wedding so, like many inexpensive areas in large cities, it is home to a vibrant artists' community. Many galleries have been founded by artists to provide a space for themselves and their peers to show their work.

What is happening to the area is really similar to what is happening in the south with the area of Neukölln
