The fort was likely designed with only three sides to maximize its defensive capabilities while minimizing resource expenditure and construction time. This configuration could have allowed for strategic positioning, taking advantage of natural barriers like cliffs or rivers for the fourth side. Additionally, it reflects a critical leadership decision to prioritize practicality and efficiency, focusing on essential defenses while still maintaining a stronghold against potential threats.
