It sparkles.
Q. "EVERY HOUR (THIS HAPPENS) AT THE EIFFEL TOWER"
You failed to answer the exact question you asked. It only sparkles at night. It does not sparkle in the day time for obvious reasons. Therefore, it does NOT sparkle EVERY hour and you answered your own question incorrectly.
According to the tower's website:
"Every evening, the Eiffel Tower is adorned with its golden covering and sparkles for 5 minutes every hour on the hour, while its beacon shines over Paris."
