The Notre-Dame Cathedral's spire used to be visible for miles.

Construction of the Notre-Dame Cathedral began in 1163, but it wasn't completed until 1345.

The spire collapsed after sustaining heavy damage from the fire.

The spire's collapse was caught on video. It was initially added to the cathedral as a bell tower in 1852.

At 226 feet high, the cathedral's two towers were the tallest structures in Paris until the Eiffel Tower was constructed in 1889.

Before the fire, visitors could climb up hundreds of steps to a gallery at the top.
