Angels have adorned rooftops of buildings for hundreds of years. Many times they are on the interior roof of a church, and they also can be found perched on top of the building, watching the people as they go inside.
Angels represent peace, hope and joy and having the honor of mounting them on a church roof is a roofing contractor’s dream. Being part of something as sacred as the construction of a place of worship has been considered an honor since the middle ages. The Free Masons was formed in that era and their story is depicted in the book Pillars of the Earth by Ken Follett, which describes the building of a fictional cathedral in London in the 1600’s that took several generations to complete. It shows how the secrets of the architectural geometry were passed along from father to son, and the calculation of where the corner stone would be placed was the most critical part of the whole project.
In modern times we see mostly simpler church construction as building a cathedral would be very cost prohibitive. For example St. Peter’s Basilica in Vatican City took 110 years to build and there are hundreds of precious jewels built right into the walls.
