Yeah, I thought so too, but apparently it’s possible.
It’s actually been done too, in October 2007, a German cathedral, first mentioned in documents in 1297, was moved using a huge trailer platform from its original emplacement by a mining company. The village it was built in 710 years ago was evacuated and was going to become a coal mining site, so, forced by German legislation, the contracting company had to spend 3 million euro to move the church to another location.
At 19,6 meters high, 14,5 meters long and weighing 750 tons, you can imagine it wasn’t an easy task for those involved. Thankfully, the church reached its new home in Martin Luther Square, in Borna, after a few days of traveling.
