Tomb of Alexander the Great: The location of Alexander the Great's tomb is an enduring mystery.  Shortly after Alexander's death in Babylon the possession of his body became a subject of negotiations between Perdiccas, Ptolemy I Soter, and Seleucus I Nicator.  According to Nicholas J. Saunders, while Babylon was the "obvious site" for Alexander's resting place, some favored to inter Alexander in the Argead burial at Aegae, modern Vergina.  Aegae was one of the two originally proposed resting places, according to Saunders, the other being Siwa Oasis and in 321 BC Perdiccas presumably chose Aegae.  The body, however, was hijacked en route by Ptolemy I Soter.  According to Pausanias and the contemporary Parian Chronicle records for the years 321–320 BC, Ptolemy initially buried Alexander in Memphis.  In the late 4th or early 3rd century BC, during the early Ptolemaic dynasty, Alexander's body was transferred from Memphis to Alexandria, where it was reburied.

Nazca Lines: The Nazca Lines are a series of large ancient geoglyphs in the Nazca Desert, in southern Peru.  The largest figures are up to 370 m (1,200 ft) long.  They were designated as a UNESCO World Heritage Site in 1994.  The high, arid plateau stretches more than 80 km between the towns of Nazca and Palpa on the "Pampas de Jumana", about 400 km south of Lima.  Although some local geoglyphs resemble Paracas motifs, scholars believe the Nazca Lines were created by the Nazca culture between 500  BC and 500 AD The figures vary in complexity.  Hundreds are simple lines and geometric shapes; more than 70 are zoomorphic designs of animals, such as birds, fish, llamas, jaguars, and monkeys, or human figures.  Other designs include phytomorphic shapes, such as trees and flowers.
