Building Borders
If your country’s borders are threatened, then it might be a good idea to construct a security border. Saudi Arabia has erected a security fence on its border with Iraq in order to keep ISIS out of their country. Additionally, with terror groups running around Yemen, Saudi Arabia built a wall in between their border as well.
Tower Of Babel
Saudi Arabia is building the Jeddah Tower, formerly named the Kingdom Tower, which is set to be the tallest building in the world. Its construction halted for a while, but is back on as of 2023. It will eventually tower over even the Burj Khalifa.
