Cologne is the fourth-largest city in Germany - and one of the oldest. A Germanic tribe, the Ubii, had a settlement here, this was named by the Romans "Oppidum Ubiorum". In 50 AD, the Romans founded "Colonia Claudia Ara Agrippinensium", the city then became the provincial capital of "Germania Inferior".

I actually have no idea who or what Bowe is.

I had the impression, that flying saucers gathered here. I saw these "reflections" quite often here. They seem to wait for the garage gate (center) to open. Maybe Bowe is somehow connected to extraterrestrial intelligence.

Bowe may be an acronym - standing for

Beyond! Our! Wisdom! Entirely!
