Gone already (Or: Seal outside of city hall)

Last month Marco and I were walking past city hall (probably on the way to get coffee at Lebkov) when we spotted something new.

A seal near the entrance to The Hague’s city hall. But when we walked past it yesterday night, it was already gone. All that was left was a pattern of studs that had held up the seal. Did it fall? Was it taken down? Stolen? Who knows…
