There's a new attraction in Old Montreal that opened it's doors this week and you're definitely going to want to check it out.
Montreal's Pointe-à-Callière Museum has recently build a brand new pavilion, but there's something rather unusual about this exhibit. It's located deep underground and can only be accessed by an underground tunnel built in 1832.
Once inside, you'll make your way beneath Place d'Youville until you reach the old remains of the Ville-Marie Fort.
And this weekend you can visit this mysterious underground cave for free on May 20-21-22.
