Calling to prayer was my term. They're are using the modern minaret "tower of voices" for essentially that purpose though. Except the prayer is not called for 5 times a day but 24/7.

Respectfully, I think that is another stretch:

"Tall enough to be seen from the highway, the tower of voices heroically marks the entry to and exit from the Park. Set on a planted mound in a clearing, within resonating rings of White Pines, the Tower houses forty white aluminum wind chimes. The continuing songs of chimes in the wind celebrate a living memory of those who are honored."

Just FYI, since you're playing so dumb. Artists and architects almost never create exact duplicates of what they're supposed to represent. To think that they would build an actual Muslim minaret to represent a minaret is foolish. Same with the crescent and star. Neither are exact, yet the representation is clear. People who know about art are able to pick up on the design cues quite easily. Things are normally abstract and created as symbolic representations. All sorts of materials are used to do this in many different ways.

Either you know that glaringly obvious fact and are playing dumb or you need to take some art and architecture courses and learn more.
