Construction workers had quite the surprise on Tuesday 21 November when they unearthed a giant swastika in Hamburg, Germany.

The men had just started working on the Hein-Kling stadium when they discovered the symbol. Made of concrete, it measures four-by-four-metres (13-by-13 foot). It is believed it was once the base to a Nazi monument.

The monument to Hitler's Third Reich had remained hidden for over 70 years underneath what is now a football field.

"It should be removed as quickly as possible," a spokesperson for the sports club told the German Agency DPA.

However, it seems the city council will have to arm itself with patience. The Nazi symbol is 1.3 feet below ground and too large to be airlifted. Workers will have to use jackhammers to destroy it.

Although Nazi monuments can be erased, it seems the ghost of Aryan rhetoric still haunts the West years after the fall of the Third Reich.

An English school for boys located in Kent came under scrutiny on 20 November after it was revealed it had created an "unsafe space" where student could talk about Adolf Hitler and Mein Kampf.

"These are not texts we wish to protect our students from but help them to consider with proper academic guidance as ways in interpreting and understanding the Twentieth Century," a spokesperson for the school told IBTimesUK.

"We are not interested in fomenting xenophobia, racism or sexism. We are interested in evaluating arguments, not putting stilts under postures," director of humanities Professor James Soderholm told the Guardian.

Simon Langton Grammar School had previously invited controversial alt-right figure Milo Yiannopoulos to speak in front of the student.
