Like all buildings which face the City street, St. Patricks Cathedral in Midtown Manhattan had
an exterior full of car exhaust, smoke, dirt and grime. In 2012, the cathedral announced it would be starting a multi-year restoration process to clean the 5th Avenue facade and revert the stone back to it's original color. In December 2014, the facelift was completed and revealed to the world. This is a time lapse of that process over the past two years, shot from above in 30 Rockefeller Plaza.
