It‘s more like the teeth have a garden in them, than the other way around.
Yes. These were part of a anti-tank defence line along the western border of WWII germany. They’ve been build between 1936 and 1940 and were supposed to be part of a several km long defence area that was supposed to stop tanks and force attackers to only use certain roads, mostly those who were guarded by heavy defence in form of large bunker and gun installations.
They are solid concrete and been literally concreted in place with solid foundations – they were supposed to trap tanks after all – so many choose not to dig them up post WWII, others were kept around as historical reminders, and many are still part of memorial paths.

The Swiss call their own [“Toblerone”](https://en.wikipedia.org/wiki/Toblerone_line), for obvious reasons.
