Looks like a copy and paste job.
The Green Cathedral or De Groene Kathedraal located near Almere in the 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 Green Cathedral is 150 m (490 ft) long and 75 m (246 ft) wide, and the mature poplar trees are about 30 m (98 ft) tall.
The planting itself is kinda ok, but taking the time to till out the same size in the forest next door is crazy
