"It at" is grammatically incorrect and doesn't make sense on its own.
Here's why:
* "It was located at" is a complete sentence. It uses a subject ("it"), a verb ("was located"), and a prepositional phrase ("at").
* "It at" is incomplete. It lacks a verb and a prepositional phrase, making it ungrammatical.
You would need to complete the sentence with something like:
* It at the corner of Main Street.
* It at the beach.
