The £160m prison gives lags a single en suite cell with its own bathroom / Europics

The £160m prison, near Oslo, Norway, gives 252 lags a single en suite cell with its own bathroom and windows without bars.

Inside the maximum security prison, authorities have lavished more than 1 million on modern art, including Banksy-style murals on the prison walls.

Governor Arne Hoidal - who opens the jail next month - told the Austrian Times: "We are very proud of what we have achieved.

"None of the windows have bars and they are made of unbreakable security glass so that people do not feel too claustrophobic."
