In the same way as the The Architectural Work of Le Corbusier, the Architectural work of G.Eiffel has been already approached? Would it be a serious idea or not in your opinion? It could cover several countries.
I didn't find any topic about this architect

You will have seen the Connection for WHS inscribed as "Multiple works of a Single Architect"?
So - Palladio, Vauban, Horta, Gaudi, Le Corbusier and FL Wright.
Leaving aside the issue of whether they all really "justify" being placed on a World Heritage pedestal, I guess that what they have in common is an innovative, coherent and developing style/technology which influenced the wider world and/or (Horta?) reflected an era/historical period, rather than merely being a collection of works which happened to be created by a single person. Some of the Nominations, of course, had problems in coming up with a subset of the oeuvres of the "great man" which satisfactorily demonstrated that!
What attributes/features would you cite as being Eiffel's particular "gift(s)" to the world of engineering and which works could do that?

Nothing in particular, i just wanted your opinion. I prefer Eiffel architecture rather than the Le Corbusier's one (or Horta). But it's just an esthetic point of view, it's not based on serious WHS criteria. But we can imagine the usage of iron like Le Havre has been classified for the usage of concrete. In Lisbon, Paris, in Corsica, and countries like Algeria, Vietnam, Hungary...

is there a decent map anywhere of the Paris: Banks of the Seine WHS which shows where the boundaries are? I'm going to spend a day or so there early next month an I've never precisely found out. Frustrating.

The UNESCO site has this one. You can zoom in on the map to see that many famous sites, from Notre Dame Cathedral to the Louvre to the Eiffel Tower are in the core zone. I personally like Sainte-Chapelle for its remarkable stained glass windows that are worth seeing by morning's light.

I think the one on the UNESCO website is pretty clear (when you zoom in): http://whc.unesco.org/document/107183
The core zone comprises the Seine river between the Eiffel Tower and Ile St. Louis, the islands in the river and the parks & buildings which lie directly on both river banks. Plus some additional notable buildings which are not directly on the river banks but close enough: the Hotel des Invalides, the Grand Palais and the Church de La Madeleine for example.
All other interesting places you may have heard about in Paris are not included.

My French isn't good at all but I think the sites on Martinique comprise of 6 zones and not just Mount Pelee?

1re aire : le massif du Piton Mont Conil et les mornes et pitons adjacents sur les communes sur Prêcheur et Grand-Rivière,

2e aire : l'édifice volcanique récent de la Montagne Pelée et ses différents versants,

3e aire : le massif du Morne Jacob et des Pitons du Carbet, la coulée forestière du Morne Rose à Fond Boucher sur les communes de Bellefontaine et Case-Pilote,

4e aire : la Presqu'île de la Caravelle à Trinité,

5e aire : la Presqu'île des Trois-îlets,

6e aire plus dispersée : constituée de 6 zones naturelles d'intérêt écologique, faunistique et floristique (ZNIEFF) du centre et du sud de l'île, toutes à très haute valeur écologique, Montagne du Vauclin, mornes calcaires de Sainte-Anne, Morne Aca, Ravine Saint-Pierre et Morne Préfontaine, Morne David et Bois la Charles, Pointe Bateau et Pointe Jean-Claude et d'îlets ou rochers de grande importance botanique ou ornithologique : le Rocher du Diamant, les îlets de Saint-Anne et l'îlet Chevalier.

Yes you're right, it says that it's made up of six areas, and the sixth one itself comprises 6 zones (1. Vauclin Mountain, 2. limestone mornes of Sainte-Anne 3. Morne Aca 4. Saint-Pierre gully and Morne Préfontaine 5. Morne David and Bois la Charles 6. Pointe Bateau and Pointe Jean-Claude) as well as a handful of rocks (the Rocher du Diamant) and islets (Saint-Anne and Chevalier).

Thanks Jasam and Zoe, I have added the locations and the link

To follow-up on this roadmap, there's https://la1ere.francetvinfo.fr/candidature-martiniquaise-unesco-bonne-voie-763725.html
The text says that Martinique, La Baie des Anges à Nice and la Maison Carrée de Nîmes are 3 candidates that battle each other for a spot in 2021. Looks like Macron handpicks the one!
For 2020 we already see the Phare de Cordouan, one from the 'old' Tentative List (2002)

Upon reading Nan's review of Cistercian Abbey of Fontenay I had to wonder when he visited Fontenay and Vezelay, because when I visited them both in late January 2020 the public transportation was not as bad as he describes. I got around without taking a taxi or hiking. But it was before the lockdown, so things may have changed. In any case, because things may come back to normal I would like to indicate here what I did.
I visited Vezelay first and then Fontenay the next day. It required one-night stay in Vezelay, but I stayed at an accommodation designed for pilgrims, so it was cheap at 12 Euros for my own room (as there was nobody else in the dorm room) for one night.

First, I took train to Sermizelles, then took a minibus from Sermizelles to Vezelay arriving there before noon. Another World Heritage Church of Saint-Jacques-le-Majeur of Asquins (on the Route of Santiago) can be seen from the bus on the way. After Vezelay this minibus was heading further south to Corbigny (the second location of the Vezelay WHS).
https://hotellerie-vezelay.fr/wp-content/uploads/2019/10/NAVETTE-SERMIZELLES-HORAIRES-2019-2020-2.pdf
The next morning I took the mini bus from Vezelay back to Sermizelles, took a train to Avallon, took a bus 119 to Semur-en-Auxois (where I had one hour between buses to check out this one of the most beautiful villages in France I have seen), and took another bus 120 to Montbard. I was in Montbard in the early afternoon.

Also, it seems like there is a direct bus between Vezelay and Montbard once a week during this summer.
https://www.viamobigo.fr/ftp/document/5fh-lr813-valide.pdf
Right in front of the Montbard train/bus station is a tourist office where I rented a bicycle for a few hours to visit Fontenay. There was no bus to Fontenay, so I just googled bicycle rental on the Google Map of Montbard. I booked this bicycle a day before from Vezelay, but booking was not necessary. It took about 30 min. to get to Fontenay. I was back at the Montbard train station by late afternoon.

Feels like you are throwing a gauntlet...

First things first, getting travel information in France is really difficult. Google, sncf, ... they all aren't complete so you have to google a lot. Possibly, you have to read French only pages (not a problem for me).


I saw the Navette (tip for anyone googling mini bus in France use Navette). But at the time of my visit the schedules seemed difficult. Essentially, it required an overnight from you for a visit that took 2h at best. To me, not being able to leave the same day points to bad connection.


Where did you find that connection? Still, morning to early afternoon sounds like a minimum 4h trip. By car the trip takes 65km/1h. Sorry, that isn't a great connection.


I didn't visit in Summer. And even then, once a week isn't really frequent.


When I visited they were closed all day. That would have been a great option, though, and I had hoped to find sth like that.

My post was meant for those who will be going to Vezelay and Fontenay in the future.
Vezelay is one of the few WHSs that are also on the list of 159 Les Plus Beaux Villages de France. (The only other WHS on the list I am aware of is Conques, but there can be more.) So I thought it was well worth spending more than few hours. I have been to only two others on the list of Les Plus Beaux Villages de France (Les Baux-de-Provence and Gordes) and loved them both.The presence of at least two national heritage sites in a village is one of the requirements to be on this list.
https://www.les-plus-beaux-villages-de-france.org/fr/nos-villages/?map=true
But unlike Els' experience in Vezelay most things were closed, as I went there in January, and because it was raining, it was difficult to see how beautiful this village was. So I even feel like going back there in summer at one point. You can easily make a day trip from Paris with the public transportation.

Probably right. And still making my point. Most things in France can be done easier as a day trip from far away Paris than a nearby city.
