Found Hidden Treasure When Renovation of British Castle

Buckingham Palace is over 300 years old, so it's no wonder to keep more than a few treasures of history.
During an ongoing renovation project, electricians working to remodel the castle find some relics of the past, including newspaper clippings and some packets of cigarettes that somehow remain perfectly stored under the palace floor boards.
According to the royal family's Twitter account, the newspaper clippings were from the Evening Standard newspaper published in 1889. As the Daily Mail noted, the clippings were published a few days before the world's first jukebox was launched.

The royal family also shared three photographs, each showing off a different cigarette case found on the floor. They-the brand was all popular in the 19th and 20th centuries and included Player's Navy Cut, Woddbine, and Piccadilly.
All these items are thought to have been thrown away by the nobles who worked for Queen Victoria.
While these items are certainly a cool invention, they are unlikely to be the last, as the renovation project at Buckingham is expected to last for years.

According to a royal family video, the project is now focusing on replacing all India's "vulcanized rubber" cables installed in the palace in the late 1940s. Wearing has made rubber wires damaged and is at risk of causing a fire in Buckingham.
And this renovation can take a long time, because most of the cable structure is smooth and complicated.
But, Queen's private residence is not part of the renovation and the palace was kept open for tourists who want to "peep" of the royal life. The $ 500 million renovation project is not expected to be completed until 2027.
