Why was Napoleon's army tearing down the wall when they found the Rosetta stone?

Napoleon's army was in Egypt as part of a campaign to expand French influence and control over the region. While conducting military operations, they were engaged in the construction of fortifications and other engineering projects, which included tearing down walls in the vicinity of the ancient city of Rosetta (Rashid). It was during this work in 1799 that they discovered the Rosetta Stone, which became crucial for understanding Egyptian hieroglyphs and ancient Egyptian civilization. The stone's discovery was a significant archaeological find amidst the military endeavors.
