The Green Cathedral or De Groene Kathedraal located near Almere Netherlands, is an artistic planting of Lombardy poplars (Populus nigra italica) that mimics the size and shape of the Cathedral of Notre-Dame, Reims, France….The work was planted by Marinus Boezem (b. 1934) on April 16, 1987 in Southern Flevoland, Nederland.
While walking there I assume you should listen to Guillaume de Machaut’s Messe de Notre Dame (1360s), composed for the cathedral at Reims (which isn’t too shabby in stone either).
Machaut survived the Black Death which devastated Europe, and spent his later years living in Rheims composing and supervising the creation of his complete-works manuscripts. His poem Le voir dit(probably 1361–1365) purports to recount a late love affair with a 19-year-old girl, Péronne d’Armentières, although the accuracy of the work as autobiography is contested.
