The United States–Mexico barrier is actually several separation barriers designed to prevent illegal movement across the U.S.-Mexico border. The barriers were built as part of three larger "Operations" to taper transportation of illegal drugs manufactured in Latin America and illegal immigration: Operation Gatekeeper in California, Operation Hold-the-Line in Texas, and Operation Safeguard in Arizona. The barriers are strategically placed to mitigate the flow of illegal border crossings along the United States-Mexico international border into the geographically vulnerable Southwestern United States. Pro-Mexican immigration groups criticize the barriers as an ineffective deterrant that inappropriately jeopardize the health and safety of those seeking illegal entry into the United States.

Hadrian's Wall


Hadrian's Wall is a stone and turf fortification built by the Roman Empire across the width of modern-day England. It was the second of three such fortifications built across Great Britain, the first being Gask Ridge and the last the Antonine Wall. All three were built to prevent military raids by the Pictish tribes (ancient inhabitants of Scotland) to the north, to improve economic stability and provide peaceful conditions in the Roman province of Britannia to the south, and to mark physically the frontier of the Empire. Hadrian's Wall is the best known of the three because its physical presence remains most evident today.

The wall marked the northern limes in Britain and also the most heavily fortified border in the Empire. In addition to its use as a military fortification, it is thought that the gates through the wall would also have served as customs posts to allow trade taxation.

A significant portion of the wall still exists, particularly the mid-section, and for much of its length the wall can be followed on foot. It is the most popular tourist attraction in Northern England, where it is often known simply as the Roman Wall. It was made a UNESCO World Heritage Site in 1987. English Heritage, a government organization in charge of managing the historic environment of England, describes it as "the most important monument built by the Romans in Britain".[1]
