Kilometre Zero

You will find a Kilometre Zero marker in many countries — in Paris it has two distinct purposes: to mark the official centre of the city; and to be the point from which all France’s highways and roads are measured from.
It’s located about 50ft outside Notre-​Dame Cathedral — directly opposite the central door of the 3 main entrances.
If the square is busy, look for a group of tourists all looking down — I bet that’s what they’re looking at!
It’s just a nice little quirky bronze star embedded in the ground, but I liked it!
