The monsters know that they lost somebody important. There's the massive Core there, and the kingdom is without a Royal Scientist.

They just can't remember who it was.

You've heard of The Tomb of the Unknown Soldier? You can build a memorial to someone, even if you don't know their name.

If even the purpose of the fountain were forgotten, it wouldn't have been a "memorial" fountain. It would just be a municipal one. This fountain -was- built to remember someone.. the builders just didn't know who.

This is probably why the public allowed Mettaton to deface the fountain later on. They found it hard to care for someone who existed like one of the vague "Warriors of Light" in Final Fantasy 14, who saved the world, yet had their memory erased from it in the process.
