Perhaps one of the most remarkable sights in France, a chapel perched on a volcanic plug. This is the Rock of Aiguilhe, on the edge of the town of Puy en Velay, in the Auvergne. The Chapelle Saint-Michel has stood there for 1042 years, since Bishop Gothescalk had it built in 962 on his return from a pilgrimage to Santiago del Compostella in Galicia. In 1955 workers found relics under the alter that had been there since it was built.
Locals in the Indian state of Meghalaya have grown bridges for 500 years. Roots and vines from the native Ficus Elastica (rubber tree) are trained across rivers, using hollowed out trees to guide the growth of the roots.
