The only definition of a microstate is a sovereign state with a "very small" population or land area.There's no international definition of "very small," although six European countries are microstates.
Liechtenstein is a little country between Switzerland and Austria. Liechtenstein is 15.5 miles 25 km long north-south. About 38,000 individuals live there.
Since Liechtenstein has few cities, its stunning Alps are visible from everywhere. National capital Vaduz, the largest town, has less than 6,000 people.
The Most Serene Republic of San Marino is a tiny city-state surrounded by Italy. San Marino is Europe's third-smallest sovereign state, at 24 square miles (61 square km).
Monaco is the richest country in the world per capita and the most famous European microstate due to its picturesque location on the French Riviera and annual Formula One Monaco Grand Prix.
Andorra is the 17th smallest country in the world, located in the Pyrenees between France and Spain. More than three times, the country could fit in London.
Malta is a Mediterranean island between Tunisia and Italy. Malta obtained independence from England in 1963, despite Neolithic indications of occupation.
