A few days ago, the famous art website Artnews selected 24 archaeological sites in the world that are most worthy of "deep digging". Among them are the well-known pyramids, Stonehenge, the Great Wall, the Sphinx, Angkor Wat, and so on.

Some relics are not well understood by the public but are also of great archaeological and artistic value. This article will introduce some of the world's most famous ancient ruins that are not so household names but still important and unique.

Mohenjo Daro was a large city built around 2600 BC in the Indus Valley in what is now the province of Sindh, Pakistan.

One of the largest ancient human settlements in the Indus Valley, the city has a standardized mud brick, rectilinear street grid, and even a well-developed sewerage system such as cesspits and public bathrooms.

The city was discovered in the early 1920s, and extensive archaeological excavations were carried out in the 1980s.

Mohenjo Daro is a very important early ancient city in the history of human civilization. The urban master plan was very advanced and very scientific, and it was a great achievement in civil engineering at the time.

It is equivalent to the metropolis of the ancient Indus Valley civilization, so many people call it "Manhattan of the Bronze Age".

But in the Sindh dialect of Pakistan, the real meaning of Mohenjo Daro is "hill of the dead".

Archaeologists mostly believe that it was the capital of an advanced civilization created by the Dravidians of ancient India before the Aryan invasion.

It is a pity that this civilization was interrupted and has not continued to this day.

Scarabrae is a Neolithic human settlement on the west coast of the main island of Scotland's Orkney Islands. In 1970, according to carbon-14 dating, archaeologists judged that these villages were built between 3180 BC to 2500 BC, more than 5000 years ago.

The Scarabrae site is small in size and mainly includes 8 stone houses with beds, dressers, and toilets. Fluted pottery, flint tools, and rune symbols were also found on the site.

Its most important significance is that it is the most complete Neolithic village found in Europe so far. Because of its complete preservation, it is also known as "Scotland's Pompeii".

The ancient city of Caral is one of the largest archaeological sites in Peru, covering 165 acres.

The ancient city of Caral was built about 4,700 years ago and is located nearly 200 kilometers north of Lima, the capital of today's Peru.

Like the Indus Valley, Egypt and Mesopotamia, it is one of the earliest regions in the world to develop ancient civilizations.

Kalar is famous for having pyramids that are older than the Egyptian pyramids. The ancient city is built around 6 pyramids, with an amphitheater and a main temple in the center.

Due to its age, the pyramid has been integrated with the surrounding rocks due to weathering. Discovered by archaeologists in 1994, it was listed as a World Heritage Site by UNESCO in 2009.

The 971-foot-long caves are located near Santillana del Mar in Cantabria, Spain. These caves were inhabited by humans between 11,000 and 17,000 years ago and continued until the European Paleolithic period.

The stone walls in the cave are painted with a large number of prehistoric cave paintings, including charcoal and color depictions of local fauna and the outlines of human hands, most of which appear on the ceiling of the cave.

Several bone carvings, stone tools, and other cultural relics have also been found in the cave.

The cave is the first cave in archaeological history with paintings of prehistoric humans，

The discovery was first announced in 1880, and until the early 20th century, many experts did not believe that prehistoric humans were capable of creating such vivid and beautiful paintings.

It was not until 1902 that the authenticity of the cave paintings was confirmed, which refreshed our understanding of the artistic capabilities of prehistoric humans, leaving an important mark not only in archaeology but also in the history of Western art.
