St. John's Cathedral, 's-Hertogenbosch
Dutch wikipedia tells us that the cathedral was under restoration "almost continuously" from 1858 to 1985. Among other things the restorers had to completed disassemble this entrance to remove iron locking pins that had rusted and swollen, cracking the stone. No cracks are visible in contemporary images, so I suppose the cracked stones were replaced.
