Logic Puzzle - True Genius - Roman Arches

Goal: Separate the two pieces.

• Their prowess at building led them to incorporate these majestic structures into other architectural marvels, resulting in the ancient world’s largest bridges, aqueducts, and stadiums. 
• Our puzzle’s four arches create a monumental challenge that builds on the Romans’ true genius.
