The World's Tiniest Nation is not Vatican but Sealand.

Welcome to Sealand!

You've almost certainly heard of some of Europe's smallest nations - San Marino, Liechtenstein, and Vatican City immediately spring to mind.

But there are a host of other tiny, self-declared independent states around the continent that haven't been recognised by other countries. The Principality of Sealand is at the top of the list.Nearly 50 years since this man-made platform split from the United Kingdom, Sealand is still going strong.

And yes, this is a country. Well, it’s more of a self-proclaimed micronation.

Population: 27

GDP: $600,000

Sealand used to be a World War II British sea fort before Roy Bates, a Major in the British army, declared it a principality. And despite there being no nation that officially recognised them as a country, Sealand continues to affirm that they have been acknowledged by Germany and the United Kingdom.

Sealand is one of the world's smallest micronations — though it is not recognised by the UK, it is effectively autonomous since it wasn't located in British territorial waters when it was established in the late 1960s.

It's off the coast of Essex, located 7.5 miles from Great Britain. The site was previously known as HM Fort Roughs, a military installation built during the Second World War.

Today, they have their own flag, government, and currency.

Sealand has a red, black and white-striped flag, while the royal coat of arms says "E Mare Libertas" or "from the sea, freedom."

The fort issues its own currency, Sealand dollars, which are worth one US dollar. The ones they sell on their online shop, however, are slightly more expensive.

They even have their own football team.

Also, visitors can be knighted there for only £99.99.

How cool would it be to say that you’re a Knight of Sealand?

But all jokes aside, let’s be honest here.

If Sealand just happened to vanish right now, no one would really care.
