The Wildebeest Migration-Kenya

Around October, nearly two million herbivores travel from the northern hills toward the southern plains, crossing the Mara River, in pursuit of the rains. In April, they then return to the north through the west, once again crossing the Mara River. This phenomenon is sometimes called the Circular Migration.
Some 250,000 wildebeest die during the journey from Tanzania to Masai Mara Reserve in lower Kenya, a total of 800 kilometres (500 mi). Death is usually from thirst, hunger, exhaustion, or predation. The migration is chronicled in the 1994 documentary film, Africa: The Serengeti.
What makes it a world class event is how the wildebeest struggle to survive with only the strongest and luckiest making it to "canaan" This event entered the Wonders of the World book in 2006.

The Dome of the Rock

Built by Caliph Abd al-Malik, the most universally recognized symbol of Jerusalem is not a Jewish or Christian holy place but a Muslim one: the Dome of the Rock. When people see its golden dome rising above the open expanse of al-Masjid al-Aqsa, they think of only one place in the world.
The Dome of the Rock is an Islamic shrine and major landmark located on the Temple Mount in Jerusalem. It was completed in 691-692, making it the oldest existing Islamic building in the world. The site's significance stems from the religious beliefs regarding the rock, known as the Foundation Stone, at its heart.

The Dome of the Rock, being among a complex of buildings on the Temple Mount (the other principal building being the Al-Aqsa Mosque), is one of the holiest sites in Islam, following Mecca and Medina. Its significance stems from the religious beliefs regarding the rock at its heart. According to Islamic tradition, the rock is the spot from where Muhammad ascended to Heaven accompanied by the angel Gabriel.

The Dome of the Rock is Jerusalem's answer to Paris' Eiffel Tower, Rome's St. Peter's Basilica, London's Big Ben and Kuala Lumpur's Petronas towers; dazzling the minds of Muslims and non-Muslims alike. The Dome of the Rock is Jerusalem.

London's Big Ben

Big Ben is the nickname for the great bell of the clock at the north end of the Palace of Westminster in London and is often extended to refer to the clock or the clock tower as well. It is the largest four-faced chiming clock and the third-tallest free-standing clock tower in the world. It celebrated its 150th anniversary in May 2009 (the clock itself first ticking on 31 May 1859), during which celebratory events took place.
The Clock also serves a major landmark for London.

The Papal Basilica of Saint Peter

The Papal Basilica of Saint Peter (Basilica Sancti Petri), officially known in Italian as the Basilica Papale di San Pietro in Vaticano and commonly known as St. Peter's Basilica, is a Late Renaissance church located within the Vatican City. St. Peter's Basilica has the largest interior of any Christian church in the world, holding 60,000 people. It is regarded as one of the holiest Christian sites. It has been described as "holding a unique position in the Christian world" and as "the greatest of all churches of Christendom"

In Catholic tradition, the basilica is the burial site of its namesake Saint Peter, who was one of the twelve apostles of Jesus and, according to tradition, first Bishop of Rome and therefore first in the line of the papal succession.
