The Cologne Cathedral (Kölner Dom) is a magnificent structure looming over the city centre, just outside the doors of the main train station.

Given its sheer size, it’s no surprise the church is seemingly under constant renovation. The last two times I passed by, in September 2015 and September 2016, there were obvious signs of repair work being done to the building’s exterior.

As you walk around the complex, you’ll notice a workshop toward the back of the church, home base for the people who keep the structure in good repair. That’s were I was able to snap this photo of some very appropriate masonry, captured on my 2015 stopover.
