There's lots to celebrate in Melbourne on the city's 181st birthday.

Unless you're one of about 4 million Melbournians, you probably didn't know that today is officially Melbourne Day.

That's right, Melbourne has its very own special day, every single year.

And to mark the occasion this morning, Lord Mayor Robert Doyle hoisted the city's flag along with some locals dressed up as first settlers.

There's also a big concert planned, with Daddy Cool frontman Ross Wilson headlining a free lunchtime bash at Federation Square.

It's all about Melbourne kicking up it's heels to celebrate 181 years since the ship Enterprize sailed from Tasmania to the north bank of the Yarra River to set up a permanent place to live.

We all know lots of the good stuff Melbourne has to offer -- the race that stops the nation, the MCG, the NGV and lots and lots of small bars.

But as the festivities kick into gear, we thought it was the perfect time to acknowledge some of the Victorian capital's often overlooked talking points.

Melbourne could have been named 'Batmania'

Melbourne ended up being names after Lord Melbourne, not John Batman, or the comic book character.

If things had been different, the first settlement that ultimately became Melbourne could have taken its name not from the caped crusader, but after John Batman, one of the first settlers in the area and a key founder of the city.

Vegemite was invented in Melbourne in 1922 and more than 1 billion jars of Vegemite have been manufactured at its Port Phillip plant. There's even a Melbourne street named after the iconic spread.

Melbourne's the birthplace of movies

The world's first feature film was made in Melbourne.

The Story of the Kelly Gang opened in Melbourne on Boxing Day 1906 and is thought to be the world's first feature-length narrative movie. The story of the famous bush ranger is said to have "enthralled audiences across the country".
