As the saying goes, "a man's home is his castle."
While this rings true for people who own a house, it was even more important for the leader in charge of a kingdom, an empire or even a republic. The reason for this is that the man in the "high castle" had much a stake. So to make sure that the country is strong, a king would build a fortress — or a wall with many fortresses — to project the centralized strength and influence of his nation throughout his realm and beyond.
Understand that a fortress is not just a building with a certain amount of walls and towers, but also can be a wall. Below is a list of the strongest fortresses ever built in the history of the world.
5. Masada, Israel
On a rocky plateau situated on a hill in southern Israel near the edge of the Judean desert, one can find the fortress of Masada. Almost all information on Masada and the siege that took place comes from the first-century Jewish Roman historian Josephus.

In 66 AD, the Kingdom of Judea was in upheaval over Rome's prolonged occupation and revolted. In doing so, a small group of rebels known as the Sicarii captured Masada after slaughtering its Roman garrison. In 72 AD, Lucius Flavius Silva, commander of the Legio X Fretensis, laid siege to Masada.
To reach the top, Lucius gave the order to build a massive ramp that was 375 feet high and 450 feet long. Once the legionaries made it to the top, they rolled the siege engines in and battered Masada's walls until they fell.
Once inside, the Romans didn't find an enemy in sight. Rather, they found over 900 dead. Only two women and five children survived.
4. Great Wall of Gorgan, Parthian/Sassanid Empire
The Great Wall of Gorgan is a fortress that remains mostly unknown. Located in northeastern Iran, the wall stretches from the Caspian Sea to the Kopet Dag Mountain Range. In total, the wall was 121 miles long.

The date of its construction is disputed. Some say it is 1,000 years older than the Great Wall of China. While little is known about the wall, the Parthians (247 BCE – 224 AD) who ruled Iran, are said to have built on the original remains of the wall.
The original height and width is unknown, but when the Sassanid Empire (224–651) overthrew the Parthians they repaired, enlarged, and added fortresses to the wall. The height of the Gorgan wall has yet to be determined. The width of the wall was between 20 to 30 feet wide and featured 30 fortresses.
What made this wall significant was that for many centuries it prevented nomads from the north, like the Dahae, Massagetae, Hephthalites and other various nomadic elements from getting in.
3. Hadrian's Wall, England/Scotland
Hadrian's Wall is well known to most casual students of history.
The Roman Emperor Hadrian in 122 AD ordered for the construction of the wall along with 16 fortresses garrisoned with static troops. The length of the wall expanded from the Irish Sea to the banks of the River Tyne near the North Sea — a distance of 73 miles.

The purpose of the wall is obvious, but as to why it was constructed, remains disputed. The reason for this is that there is no clear evidence that suggests Roman Britain, south of the future wall, was under any real substantial threats — even though there had been some minor rebellions in the province and within the Roman Empire. This was probably the reason why Hadrian built the wall — as a symbol and reminder that it is best to separate one from the barbarians.
Hadrian's Wall would provide Roman Britain security from the Celtic/Pictish tribes in the north until Rome abandoned Britannia in 410 AD.
2. Walls of Constantinople
In 324 AD, Emperor Constantine I moved the capital from Rome to the small port town of Byzantium and renamed it Constantinople. The reason for this move was to be closer to the eastern portion of the Roman Empire due to its lucrative trade.
To ensure the safety of this second Rome, Constantine issued an order to build of a wall. The Wall of Constantine was laid out in a series of four rows, with the inner two featuring towers 50 feet apart.
While very effective in repelling invaders, the Roman Emperor Theodosius II decided to expand the walls. The Theodosian Walls consisted of two — an inner and outer wall — which consisted of 96 towers. The inner wall was 40 feet high while the outer wall stood at 30 feet high.
The walls of Constantinople paid off for many centuries and were able to throw back 12 sieges from 559-1203 AD. However, the city was captured in 1204 during the fourth crusade, but afterward was able to withstand five more sieges until that fateful day in 1453, when the Ottoman Turks bashed down the walls and captured the city.
1. Great Wall of China
The Great Wall of China needs no introduction. Many assume that the Great Wall was built and finished during the lifetime of a Chinese emperor. Instead it was constructed by multiple emperors over 1,000 years.
The height, length, and thickness of the wall — or walls — vary, depending on which emperor built it and how much they could afford.
For example, once the Ming dynasty (1368-1644) pushed out the Mongols, they set about to expand and enlarge the Great Wall. The total length of the Great Wall under the Ming was over 5,000 miles long and 25 feet high and 15 - 30 feet thick at the base. If one were to take the wall and line it up, the length would be over 13,000 miles, according to study in 2012.
While the Great Wall looks good, it provided only temporary protection. The problem was that due to its size, it was too cumbersome and too costly to man.
The purpose of the Wall was to keep nomads out from the north. Instead, it kept the people of China isolated within and the wars that came with it.
The Mongols, however, just went around it during their invasion in 1211. The Ming would later enhance the wall, but it didn't make a difference when the Manchu invaded in 1644.
From that point on, the Great Wall was more of a monument to look upon with amazement.
