It's been more than a week since the Notre Dame cathedral caught fire, and French investigators said they have yet to rule out any potential causes of the blaze, Reuters reports.

  • "Investigators are expected to search through the fire-damaged cathedral for remains of cables, lights or parts of circuitry that might give clues," The Guardian reports.

The big picture: Several potential causes still linger — electrical lifts from the outside of the building, electrical wiring on the inside and cigarette butts found inside. Officials believe the cause was possibly a short circuit linked to renovation.

Notre Dame was hardly the first European gem consumed by fire, and authorities are increasingly warning that it won't be the last.

Why it matters: These civilizational achievements are also key sources of revenue in old Europe, the AP reports: "Tourism in Britain and France alone amounts to about 7% of their Gross Domestic Product, good for around 150 billion euros and 170 billion euros (around $170 billion and $190 billion) a year."
