I love when a museum makes learning fun. The French Monuments Museum (FMM, for brevity here) in Paris gives a presentation that is visually stunning, and presents enormous amounts of information to those who look deeply. The museum houses plaster casts taken from the sculpture and architectural details of selected buildings and monuments in France, ranging from small Romanesque churches to major public monuments. To enter the FMM is like walking through a chapter of a beautiful, modern, art-history encyclopedia: the life-sized casts (called "moulages" in French) are presented chronologically, so that you can witness the evolution of style, but you can also move back and forth among them to notice the recurrence of certain themes and compare their treatment by region. The style of the museum itself is striking: the moulages are mostly a rich cream color; the walls are white or deep red; light pours through ceiling-to-floor windows. The display is thoroughly modern; quite different from its subject matter.

In more ways than one, the gallery gives the viewer an opportunity to time travel. The plaster casts were taken over a period of 140 years beginning in the mid-19th century to conserve a record of sculptures recognized as endangered by wars, vandalism, and pollution. So, not only do the moulages give the viewer a chance to walk through time by going from the Romanesque facades at the exhibition's entrance to the 19th century examples at the other end of the building, they also allow one to see these monuments as they were in a time of earlier preservation.
My 2018 photos of Moissac Abbey's portal show sculptures terribly melted by acid rain. The moulages in the museum allowed me to see them in a better state, and thus I was able to decipher themes and images I couldn't make out on the current-day real thing. To visit the museum is to experience the art and architecture in circumstances quite at odds with the state of the pieces in situ. The casts are pristine, evenly-lit, and they dwell among many examples of their kind. If you were to see the originals in person (if they still exist), you would find them isolated in an urban or touristic setting, in deep shadow or glaring light, and generally deteriorated.
Here are two images of the entry to modern-day Moissac Abbey: As one enters the church, on either side one finds near-life-sized figures in bas-relief. They are badly-stained and eroded, but research had prepared me to decipher them. On one's left are representations of vice, and on one's right, representations of virtue.

Compare the originals to the moulages of the same walls from over 100 years ago.

The faces and the small symbolic objects are much clearer in the 19th century cast. On the building today, a scholar could get a general idea of what was happening on each side (by knowing about Romanesque style and typical Christian art motifs), but the comparatively pristine cast shows without ambiguity that on the left is a depiction of Avarice (the demonic soul with a money-bag around his neck) and Lust (an emaciated woman with snakes biting her breasts and covering her genitals--a common image known as La Femme aux Serpents). On the right-side wall, there are contrasting tableaux depicting virtues --one of the Gifts of the Magi (an act of generosity), and another of the Annunciation (an assertion of Mary's chastity).
In the museum, one can pass through this plaster portal, and have an experience closer to that of medieval Christians, because the narrative is more clear: every parishioner must choose between evil and good, and entering into the church provides a chance to avoid one and hew more closely to the other. Because of the dirt and erosion in today's state of the actual abbey, it is easy to pass by the portal figures and shrug, because it's so difficult to decipher them.
One can learn and enjoy looking at similar depictions from different regions of France. The representation of Original Sin in L'Eglise Sainte Madeleine is over 200 kilometers (125 miles) from the one in Notre Dame du Port; and it is from different workshops, with different approaches to depicting nudity, and different levels of detail in carving both the snake and the fruit of the tree.
