Why it call "SQUARE " and it is a ROUND building? Did the persons who got to name it go to preschool, kindergarten, or 1st grade? There seems to only be a few shrubs in planters. Why the word GARDENS ?

Madison Square Garden used to be located at where the current Madison Square Park is, where back then, it was square and in a garden setting. It outgrew its original size and was relocated to where it is currently now, retaining its original name.

But most properties are squares. The Pentagon is a pentagon; different so naming it such is Ok.

Lol. Don't know

It's at Herald SQUARE.

The property itself is square.
