In 2016, Queen Elizabeth II received an unusual yet significant birthday present: tunnel-drilling equipment used for the Crossrail project, a major train construction initiative in central London. This high-tech machinery, valued at an impressive $15 million, symbolizes the innovative spirit of modern engineering and the importance of infrastructure development in the UK.

Undoubtedly, this is one of the strangest gifts Queen Elizabeth II ever received. Along with the tunnel-drilling equipment, Crossrail also "sent the Queen a tooth from a tunneling boring machine called Elizabeth," as reported by The Mirror.
However, the fate of the machine and its current location remain a mystery. It’s unclear what the Queen ultimately did with this unique contraption, adding an air of intrigue to this unusual royal gift.
