Looking for the name of a park or island in Paris known for marriage proposals. Been therebut can't recall it

Question

Looking for the name of a park, possibly an island on the Seine, known for being a place of many marriage proposals - i was there a long time ago, but can't recall the name. THANKS!

Answer 1

Île de la Jatte in Neuilly-sur-Seine ? or the little island on Bois de Boulogne lake?

Answer 2

Parc de Bagatelle?

Parc des Buttes Chaumont?

Parc Monceau?

Here are 2 links showing all the Parks and Gardens in Paris.

You might recognize the one you are looking for.

If it was an island, then it was most probably somewhere in the surburb. May be "l'ile de puteaux"?

Answer 3

the island on the Seine is named "Île de la Cité" but I'm not sure it's well known for marriage proposals

Answer 4

Maybe it is the small Square du Vert Galant, near the statue of Henri IV on the Ile de la Cité.
