The earthquake that struck Portugal’s capital on November 1st, 1755, became known as the Great Lisbon earthquake due to the vast destruction it produced. The quake’s impact was made worse because it was All Saints Day, meaning that many thousands were attending mass at church. The churches, like many
other buildings, could not withstand the power of the tremor and collapsed, killing thousands. Afterwards, a tsunami estimated at 6 metres high struck. Roughly 80,000 perished due to fires caused by collapsing structures. Many famous literary figures and philosophers dealt with the quake in their work, such as Emmanuel Kant, who sought to provide a scientific explanation for what happened.
