The wonders are about to disappear due to the harsh weather

Places like the Roman arena, the Statue of Liberty, and the Sphinx . are still bracing themselves against the harshness of the weather.

Under the harsh impact of the weather, many historical relics in the world have been degraded over time. Please also review some of the famous places and historical sites that may not pass the "scary test" of time according to the summary of the Livescience page below.

1. The Colosseum, Italy

The Colosseum was built between 70 and 80 in Rome, Italy. This was once a place where Roman gladiators had life-and-death battles. Today, the Colosseum is voted as one of the new world wonders by over 100 million people around the world.

However, this historical site is currently continuing to fight for its own survival, with an unequal opponent being natural.

According to international meteorologist Jim Andrews, low temperatures, accompanied by snow and ice, often appear in Rome. When snow falls, snow will collect on the rock surface, then melt into water when the temperature rises. Water seeps through the rocks and when cold air comes in, the water freezes, the volume increases, causing the stone to crack.

He said that the harsh nature will gradually erase each stone of the monument, making the more than 1,900 year old wonders soon collapse in the near future, without human intervention.

2. Temple of Apollo Epicure, Greece

The Apollo Epicure Temple is one of the many temples of Apollo, because it is one of the important gods of Greece. Legend has it that the temple was built around the years 420-400 BC, after the god saved people from a plague that was devastating the entire land.

Temple of Apollo Epicure is located on a hill of the Peloponnese peninsula, Greece, about 1,131m above sea level.

According to Andrews, the Peloponnese area is relatively humid due to its mountainous terrain. Winter temperatures do not drop too low. However, the temple is located at the highest point near the peninsula, temperatures can reach freezing in winter.

Archaeologists also found a lot of rainwater deposited in marble holes. This means that the Temple of Apollo also bears the same risk as the Italian Coliseum - the low temperature makes the water soaked in the ice freeze, increasing the volume, causing the stone to crack.

3. Monument Ulysses S. Grant, USA

The monument commemorates General Ulysses S. Grant - who won the Civil War in 1861 and is also the 18th President of the United States erected in Washington, DC, USA. The memorial was started in 1902, located on the side of the US Congress (Capitol Building).

This is one of the most obvious examples of the effect of acid rain on copper metal. President Grant's statue was made mainly of copper, with a small amount of tin.

The amount of carbonic acid in rainwater will react with copper, forming a blue CuCO ₃ layer covering the statue. According to Andrews, with the impact of hot and humid environments, chemical reactions even occur faster. As a result, the bronze monument was significantly eroded.

Fortunately, according to reports from the American National Park, every year the monument is covered with wax, to prevent direct contact of rainwater.

4. Statue of Liberty, USA

The Statue of Liberty is almost a symbol of New York City, USA, located on Liberty Island - Freedom Island in New York Harbor. The statue of the goddess inaugurated in 1886, is a gift from France dedicated to the United States, in recognition of the 'friendship spirit established in the American Revolution'.

After years of exposure to nature, the Statue of Liberty is currently suffering from severe effects. Because it was made entirely of copper, after many years of 'showering', the statue had a metallic layer of green covering the outside.

Air pollution also contributes to chemical corrosion. In 1937, the authorities had to perform remodeling due to leaking water inside the statue, and maintaining it regularly to protect the statue from the more serious effects of nature.

5. Statue of Sphinx -The Sphinx

Built long ago in Egypt, in the period of the Old Kingdom (Old Kingdom), in 2686 - 2134 BC, the Sphinx is now severely eroded over time.

The terrain around Nhan Su statue slopes to the east, causing rainwater to flow mainly from the west, causing the area's rocky area to erode for a long time. Besides, saline groundwater sources under the ground increase humidity, causing significant impacts on the structure of the statue.

But water is not the only agent, but also wind and sand. Mr. Andrews said, 'Wind speed in the desert is quite large, causing sand to be blown away, over time it will erode anything'.
