In our clarification journey along the WHS with many locations, we have arrived at the Routes of Santiago de Compostela in France.

The process as described here has been followed:
1. All components now have a short description
2. All components now have the exact official name.
3. A division into 3 tiers has been made.
4. The selection has been verified by the reviewers' favourites on this site, these were:
- Conques (Abbey Church of Sainte-Foy): Often cited as the highlight of the entire list. The Romanesque portal and the treasury are considered world-class.
- Le Puy-en-Velay: A major "hotspot" for the community. It features the Cathedral of Notre-Dame and the Hôtel-Dieu. Reviewers note its unique volcanic landscape and religious importance as a primary starting point.
- Rocamadour: Mentioned alongside Conques as a must-visit location that makes travelers "feel the history." The site is vertically integrated into a cliffside and remains a powerful pilgrimage destination.
- Saint-Guilhem-le-Désert: Recommended for its stunning Romanesque architecture and the nearby Pont du Diable (Devil's Bridge), which is also an inscribed component.
- Toulouse (Basilica of Saint-Sernin): Noted as one of the largest and most significant Romanesque churches in Europe.
- Moissac (Abbey of Saint-Pierre): Famous for its cloister and porch, which are considered masterpieces of Romanesque sculpture.

So we end up with a list of 20 tier 1's: https://www.worldheritagesite.org/blog/guide-to-the-routes-of-santiago-in-france/. Comments are welcome, here or in the blog comment box.

I mistakenly said above (now corrected) that the tier 1 ones are all Michelin 3 stars.
Gemini seems a bit hit and miss here, so we'd better continue with the proposed list with the experts. Any locations that seem to be missing, or should not be in this top 20?

Single entries
Auvergne-Rhône-Alpes
868-001 Cathédrale Notre-Dame Le-Puy-en-Velay. This striking volcanic-stone cathedral is the starting point of the Via Podiensis, the most popular route in France today. Its unique Moorish-influenced architecture reflects the cultural exchange between France and Spain.

Bourgogne-Franche-Comté
868-004 Eglise prieurale Sainte-Croix-Notre-Dame. Once the second largest church in France after Cluny, this priory was a massive 'daughter' house that managed pilgrim traffic over the Loire. Its surviving towers still dominate the river crossing.

Nouvelle-Aquitaine
868-016 Eglise Saint-Pierre Aulnay. Considered one of the most beautiful Romanesque churches in France, its portal is a riot of medieval imagination. It served as a visual encyclopedia for pilgrims resting in the Saintonge countryside.

868-021 Cathédrale Saint-Front Périgueux. Its unique five-domed Greek cross plan makes it one of the most distinctive churches in France. It served as a massive milestone on the Limoges Route, offering a vision of Eastern Christian architecture.

868-027 Abbaye Notre-Dame de la Sauve Majeure La Sauve. This 'Great Forest' abbey was a massive monastic complex that governed many smaller hospitals along the pilgrimage trails. Today, its majestic ruins and expressive capitals showcase the wealth generated by the route.

868-037 Eglise Sainte Marie Oloron-Sainte-Marie. The stunning Romanesque portal of this cathedral depicts the transition from the mundane world to the sacred. It was the final major spiritual preparation point before the climb to the Somport Pass.

Occitanie
868-044 Abbatiale Sainte-Foy Conques. A masterpiece of Romanesque art, this abbey held the relics of St. Foy and was a primary stop on the Puy Route. Its tympanum of the Last Judgment served as a visual sermon for medieval pilgrims.

868-049 Ancienne abbatiale Saint-Gilles-du-Gard Gard. Once the fourth most important pilgrimage site in Christendom, this abbey served as the gathering point for pilgrims on the Regordane Way. Its facade is one of the most sophisticated examples of Romanesque sculpture in existence.

868-050 Ancienne cathédrale Notre-Dame Saint-Bertrand-de-Comminges. Perched on a hill, this 'Cathedral of the Pyrenees' was a vital stop for those crossing the central mountains. It features a stunning mix of Romanesque and Gothic styles with world-class wood carvings.

868-052 Basilique Saint-Sernin Toulouse. The largest Romanesque church in Europe, it was designed specifically to manage large crowds of pilgrims viewing its vast collection of relics. It served as the model for the cathedral in Santiago de Compostela itself.

868-059 Ancienne abbaye de Gellone Saint-Guilhem-le-Désert. Nestled in a rugged canyon, this abbey housed a relic of the True Cross, drawing massive crowds on the Arles Route. It represents the austere beauty of early Languedoc Romanesque architecture.

868-060 Pont Valentré Cahors. A fortified bridge with three towers, it is a masterpiece of medieval military and civil engineering. It protected the city while facilitating the movement of thousands of pilgrims across the Lot river.

868-061 Cathédrale Saint-Etienne Cahors. Featuring two massive domes, this cathedral reflects the influence of Byzantine architecture on the southern French pilgrimage routes. It protected the 'Holy Shroud' of Christ, making it a highly prestigious stop.

868-064 Cité religieuse Rocamadour Built into a sheer cliff, this sanctuary was one of the most famous shrines in the Middle Ages, often visited as a major detour. Pilgrims climbed the steps on their knees to honor the Black Madonna before continuing toward Spain.

868-070 Abbatiale Saint-Pierre et cloître Moissac. Famous for its world-renowned cloister and south portal, this abbey was a major intellectual and spiritual hub on the route to Spain. The intricate carvings provided pilgrims with spiritual meditation through art.

868-072 De Nasbinals à Saint-Chély-d'Aubrac (17 km). This 17km stretch across the Aubrac plateau is perhaps the most iconic landscape of the entire French route. The desolate, windswept beauty tested the endurance of every medieval traveler.

Double WHS
These Tier 1-components are also inscribed on their own right:

868-006 Basilique Sainte-Madeleine Vézelay. As the starting point of one of the four main routes, this basilica housed the purported relics of Mary Magdalene. Its light-filled nave was designed to inspire awe in the thousands who gathered here to begin their journey.

868-007 Cathédrale Saint-Etienne Bourges. This massive, five-aisled cathedral was a key landmark on the central route through France. Its lack of a transept created an uninterrupted space that echoed the focused, linear journey of the pilgrim.

868-012 Cathédrale Notre-Dame Amiens. Though far north, this cathedral housed the head of Saint John the Baptist, a relic that drew pilgrims from across Europe. Its immense Gothic nave represented the 'Heavenly Jerusalem' that pilgrims sought on earth.

868-015 Le Mont-Saint-Michel Manche. While a destination in its own right, 'The Marvel' was the start of the 'Plantagenet' route to Spain. Many pilgrims visited the Archangel before turning south to visit the Apostle James.

WHS: Funerary and memory sites of the First World War

Component: Cimetière militaire français Germania

The description in our map talks about it being "A specialized German cemetery". But the cemetery is in fact a French military cemetery. I would suggest the description has to be changed.

Done: Former German army camp, where, after the deadly fighting at Reichackerkopf (1915-1916), French soldiers who fell in the vicinity or died as prisoners in the German hospital were buried. They were later exhumed and transferred to larger nearby sites.
