10 "Impossible" Monuments Built Before Modern Machines

A single block of granite heavier than a jumbo jet, raised upright in under two hours in 1832. A cathedral abandoned for 400 years with a crane still on its tower. A palace of glass half a kilometre long, built in 39 weeks and lost in a single night. There is an official answer for every one of these monuments: a date, an architect, a tidy line in a history book. But put these ten side by side and something strange begins to show. The same impossible weights. The same impossible speed. And in almost every case, the builders left a clue sitting in plain sight. Tonight we follow those clues: what the official story says, what the records actually show, and the questions still hanging in the air.
