The Seven Wonders of the World has historically been a listing of seven sites known to the Ancient Greeks as the most notable locales in their known world.

Since then, many have developed lists of the "modern" Seven Wonders of the World. The only list that really stands out and has stood the test of time for more than a decade is the Seven Wonders of the Modern World, developed by the American Society of Civil Engineers.

2) : -The Great Pyramid of Giza
The Great Pyramid of Giza (called the Pyramid of Khufu and the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. Egyptologists believe that the pyramid was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu (Cheops in Greek) over an approximately 20 year period concluding around 2560 BC. Initially at 146.5 metres (481 feet), the Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called Queen's Chamber and King's Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the only pyramid in Egypt known to contain both ascending and descending passages. The main part of the Giza complex is a setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

The Hanging Gardens of Babylon were considered to be one of the Seven Wonders of the Ancient World, and the only one of the Wonders that may have been purely legendary. They were purportedly built in the ancient city-state of Babylon, near present-day Al Hillah, Babil province, in Iraq. The Hanging Gardens were not the only World Wonder in Babylon; the city walls and obelisk attributed to Queen Semiramis were also featured in ancient lists of Wonders.

The gardens were attributed to the Neo-Babylonian king Nebuchadnezzar II, who ruled between 605 and 562 BC. He is reported to have constructed the gardens to please his homesick wife, Amytis of Media, who longed for the plants of her homeland. The gardens were said to have been destroyed by several earthquakes after the 2nd century BC.

The Hanging Gardens of Babylon are documented by ancient Greek and Roman writers, including Strabo, Diodorus Siculus, and Quintus Curtius Rufus. However, no cuneiform texts describing the Hanging Gardens are extant, and no definitive archaeological evidence concerning their whereabouts have been found.

 Ancient writers describe the possible use of something similar to an Archimedes screw as a process of irrigating the terraced gardens. Estimates based on descriptions of the gardens in ancient sources say the Hanging Gardens would have required a minimum amount of 8,200 gallons (37,000 liters) of water per day. Nebuchadnezzar II is also reported to have used massive slabs of stone, a technique not otherwise attested in Babylon, to prevent the water from eroding the ground.

The Lighthouse of Alexandria (in Ancient Greek, ὁ Φάρος της Ἀλεξανδρείας), was a tower built between 280 and 247 BC on the island of Pharos at Alexandria, Egypt. Its purpose was to guide sailors into the port of Alexandria.

With a height variously estimated at somewhere between 393 and 450 ft (120 and 140 m), it was for many centuries among the tallest man-made structures on Earth. It was one of the Seven Wonders of the Ancient World.

The Mausoleum at Halicarnassus or Tomb of Mausolus (in Greek, Μαυσωλεῖον τῆς Ἁλικαρνασσοῦ) was a tomb built between 353 and 350 BC at Halicarnassus (present Bodrum, Turkey) for Mausolus, a satrap in the Persian Empire, and Artemisia II of Caria, his wife and sister. The structure was designed by the Greek architects Satyros and Pythius of Priene.

The Mausoleum stood approximately 45 m (148 ft) in height, and each of the four sides was adorned with sculptural reliefs created by each one of four Greek sculptors — Leochares, Bryaxis, Scopas of Paros and Timotheus. The finished structure of the mauloseum was considered to be such an aesthetic triumph that Antipater of Sidon identified it as one of his Seven Wonders of the Ancient World.

The word mausoleum has now come to be used generically for grand tomb.

The Temple of Artemis (Greek: Ἀρτεμίσιον, or Artemision), also known less precisely as the Temple of Diana, was a Greek temple dedicated to a goddess Greeks identified as Artemis and was one of the Seven Wonders of the Ancient World. It was located in Ephesus (near the modern town of Selçuk in present-day Turkey), and was completely rebuilt three times before its eventual destruction in 401. Only foundations and sculptural fragments of the latest of the temples at the site remain.

The first sanctuary (temenos) antedated the Ionic immigration by many years, and dates to the Bronze Age. Callimachus, in his Hymn to Artemis, attributed it to the Amazons. In the 7th century the old temple was destroyed by a flood. Its reconstruction began around 550 BC, under the Cretan architect Chersiphron and his son Metagenes, at the expense of Croesus of Lydia: the project took 10 years to complete, only to be destroyed in an act of arson by Herostratus. It was later rebuilt.

Antipater of Sidon, who compiled the list of the Seven Wonders, describes the finished temple:

I have set eyes on the wall of lofty Babylon on which is a road for chariots, and the statue of Zeus by the Alpheus, and the hanging gardens, and the colossus of the Sun, and the huge labour of the high pyramids, and the vast tomb of Mausolus; but when I saw the house of Artemis that mounted to the clouds, those other marvels lost their brilliancy, and I said, "Lo, apart from Olympus, the Sun never looked on aught so grand"
