More than 100 tonnes of gold were returned from London to Poland as part of a very secret repatriation mission.
The transport, worth about $ 5 billion, was transported from a secret location near the capital to an unknown airport in London, accompanied by a police escort and from a helicopter, then boarded a cargo plane and flew to Poland.
At the beginning of the Second World War, all Polish gold reserves were secretly transported to three continents for storage in London, New York and Ottawa.
Poland has now seen the gold that had been preserved in the UK and was returned to it and placed in a highly secure place.
Upon arriving in Poland on November 22, the gold was loaded into three armored vehicles and accompanied by a full procession of undisclosed vaults.
It took eight trips to bring gold to the Narodowy Bank Polski, the country's central bank, where it will now be kept.
Each ingot was a standard London Good Delivery ingot weighing 12.5 kg and bearing a serial number and a marker indicating where it had been produced.
G4S Cash Solutions UK has managed the operation. John Lennox, director of the company, said: "The gold movements have been carefully planned in coordination with everyone, including the police, the Bank of England, the Narodowy Bank Polski and G4S .
"Given the sensitivity of this operation, we had to be ready for anything, plans can change on short notice, have a strong team, flexible and professional drivers, and make sure everyone is on the right track. day regularly means that the operation has been a complete success. "
G4S chief executive, Julian Haskard, called the repatriation operation "historic day in the gold industry".
The bank official of Poland confirmed that the transfer of gold was completed and added that a commemorative coin would be struck to celebrate the event.

In addition to the original ingots, Poland announced last year that it would buy an extra 100 tonnes of gold, which would give a boost to the reserves.
According to Bloomberg, the country had $ 121.9 billion (£ 93.7 billion) in its official reserves, including gold, at the end of October.
