Which structural inefficiency arises when ashlar masonry fortification walls exceed practical heights?

💡 Explanation

When ashlar walls become too tall, significant compression loading occurs via lithostatic forces which cause concentrated stress at the masonry courses contacting ground surface because material strength is limited. Therefore increased stress results, rather than instability, reduced effectiveness, or weathering which depend on different geological/environmental factors.
