The 94-year-old monarch and his grandson, Prince William, visited the Defense Science and Technology Laboratory in Portonauna.
The queen and the prince did not wear face masks, only the recommended distance of two meters. It is estimated that all participants in the event underwent a Covid-19 test.
The Queen meets with scientists involved in classified research to protect Britain from the terrorist threat.
The queen arrived by helicopter, separate from William, who arrived by car.
The queen looked full of energy in her soft pink dress. The costume, of course, had a hat with a gold decor.
