A three-year restoration project at St. Patrick's Cathedral in New York is wrapping up, just in time for a late September visit from Pope Francis. Most of the scaffolding has already come down and officials are steadfast in saying it will be done in time.

The $175 million project has been a huge undertaking. The entire exterior was covered in scaffolding, all the way to the top of the two 330-foot-tall spires, and washed clean of decades of dirt. Scaffolding also blanketed the inside, as workers cleaned and repaired the 3,700 individual panels in 75 stained glass windows. The bronze doors at the Fifth Avenue entrance were also restored.

St. Patrick's is the seat of the Roman Catholic Archdiocese of New York and one of the country's most well-known churches.
