Do you know the smallest country in the world?

The land area of the planet is estimated at 29.2% of the Earth's surface, and there are countries that we cannot recognize in maps, due to their small size, where the size of one of them does not exceed a neighborhood in other countries.

Vatican State:

The Vatican State is one of the smallest countries in the world, and although it follows Rome militarily, it is a separate sovereign state, located entirely in the heart of the Italian capital Rome, surrounded by Rome on all sides and separated from it by private walls, and an area of 108 acres, or about 0.44 A square kilometer, with a population of only about 1,000 people, and the strangest phenomena in the Vatican are devoid of children, as all of its inhabitants are monks and nuns who prevented themselves from getting married. The Italian army is responsible for defending the security of the Vatican, as the Vatican has no naval, air, or land forces, while the forces responsible for the Vatican's internal security are the Swiss Guard, which has a population of about 100 people.
