Love-locks on the Pont de l'Archeveche, crossing from the Latin Quarter to the Cité island.
Love-locks glam up a couple of Seine bridges, the idea being to write (or even better, engrave) a romantic message on a padlock, lock it to the wire fencing and throw the key into the river. Voila! Everlasting love!
Notre Dame's famous 'flying buttresses' seen from the east side park Square Jean XXIII.
Another view of the Old Lady from the Left Bank, Latin Quarter.
Incidentally it's called the Latin Quarter because France's best university, the Sorbonne, is here and the students used to communicate mainly in Latin.
Early afternoon in the west-side plaza outside the Notre Dame entrance (right side door). Tour groups are lining up to get inside. Get there between 8am - 9am and avoid the lines!
Don't neglect the facade, it's loaded with wacky visions of hell as well as heaven! Next, Notre Dame interior.
Try to get to the Notre Dame in the morning 8 to 9 o'clock to pre-empt the queues and crowds, especially for going up onto the roof.
Access to the roof opens, for a fee or with Museum Pass from April - September 10am to 6.30pm; October - March 10am to 5.30pm. Start queuing at 9 or 9.30am in summertime.
Sunday afternoons are often enlivened with free organ recitals.
