In practice, mountains in Scotland are frequently referred to as "hills" no matter what their height, as reflected in names such as the Cuillin Hills and the Torridon Hills . In Wales, the distinction is more a term of land use and appearance and has nothing to do with height. For a while,

Today, a mountain is usually defined in the UK and Ireland as any summit at least 2,000 feet or 610 meters high, while the UK government's Countryside and Rights of Way Act 2000 defined mountainous areas (for the purposes of open access legislation) as areas above 600 meters (1,969 feet). Some definitions include

Battles for the possession of high ground have often resulted in heavy casualties to both sides, such as the 1969 Battle of Hamburger Hill during the Vietnam War , the Battle of Stalingrad and Battle of Peleliu during World War II , and the 1969 Kargil War between India and Pakistan. The Great Wall of China is an enduring example of hilltop fortification. It

These include: Many settlements were originally built on hills, either to avoid floods (particularly if they were near a large body of water), for defense (since they offer a good view of the surrounding land and require would-be attackers to fight uphill), or to avoid densely forested areas. For example, Ancient Rome was built on seven hills , helping to protect it from invaders. Some settlements, particularly in

The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than 1,000 feet (304.8 meters) above sea level .
