The **Pharos of Alexandria**, constructed by Ptolemy I in the third century BC on Egypt’s Pharos Island, was a towering white stone **lighthouse**, estimated to be over 330 feet tall. Its fame and importance for guiding ships into the busy harbor were so great that the word 'pharos' became the root for 'lighthouse' in many Romance languages.

The **Colossus of Rhodes**, a 110-foot bronze statue of the Greek sun god **Helios**, was erected between 292–280 BC at the harbor entrance in Rhodes, Greece. Built by Chares of Lindos, it took 12 years to construct but collapsed in an earthquake in 225 BC, just 56 years after its completion.

The Mausoleum at Halicarnassus, constructed in 353 BC in Bodrum, Turkey, was a 140-foot **tomb** built by Queen Artemisia for her deceased husband, **King Mausolus**, a satrap (governor) in the Persian Empire. Its grandeur and opulence were so remarkable that its name inspired the generic term 'mausoleum' for any large, stately tomb.

The Temple of Artemis, built after 350 BC in the ancient city of **Ephesus**, which is located in modern-day **Turkey**, was dedicated to the Greek goddess of the moon and the hunt. With a 400-foot base and over 100 columns rising 60 feet, it was a pinnacle of beauty until its final destruction by the Goths in 262 AD.

The Statue of Zeus, sculpted by Pheidias around 432 BC in Olympia, Greece, was a 43-foot **chryselephantine** masterpiece. This term refers to a sculpture made of **gold and ivory** over a wooden frame, giving the statue its majestic appearance. Adorned with jewels and symbolic elements, it was a marvel of ancient artistry, though it was later destroyed.

The Hanging Gardens of Babylon, built around 600 BC in modern-day Iraq, were traditionally attributed to **King Nebuchadnezzar II** for his wife, Queen Amyitis, to console her for her homesickness for the mountains of Media. This multi-tiered structure, rising up to 300 feet, was designed to mimic her homeland’s lush landscapes. However, some modern scholarship questions their historical reality or location.

The Pyramids of Giza, constructed around 2690 BC for Pharaoh Khufu, are the only surviving wonder of the ancient world. Located southwest of Cairo, Egypt, the Great Pyramid originally stood at 481 feet but now measures 450 feet due to erosion and loss of its capstone. Its enduring presence is a testament to ancient Egyptian engineering.

Continental plateaus are vast, flat, elevated areas located in continental interiors or covering entire continents. The Antarctic Plateau, which is mostly covered by the continental ice sheet, is a prime example.

The Meseta Central ('Central Plateau') is a vast plateau in the heart of the Iberian Peninsula, covering a large part of central Spain and dominating its landscape.

The Western Plateau is a huge, ancient shield that covers the western two-thirds of the Australian continent, dominating its geography.
