Lisbon Temple

The Lisbon Temple was a First Civilization temple located beneath the Carmo Convent in Lisbon, Portugal.

On 1 November 1755, the Assassin Shay Cormac arrived at the Carmo Convent to explore the temple on orders of his Mentor, Achilles Davenport. After opening the entrance to the temple, Cormac tried to take the Piece of Eden housed inside, but unknowingly activated the temple's defense mechanism.

The temple then created a seismic event that almost completely destroyed Lisbon and the surrounding areas, killing thousands of civilians. Shay Cormac was able to escape the earthquake by navigating through the city and escaping to the Assassins' ship.
