Taj Mahal in Morning

The Taj Mahal (pronounced /tɑdʒ məˈhɑl/; Hindi: ताज महल; Persian/Urdu: تاج محل) is a mausoleum located in Agra, India, built by Mughal Emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal.

The Taj Mahal (also "the Taj") is considered the finest example of Mughal architecture, a style that combines elements from Persian, Ottoman, Indian, and Islamic architectural styles. In 1983, the Taj Mahal became a UNESCO World Heritage Site and was cited as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage."

Taj Mahal

While the white domed marble mausoleum is its most familiar component, the Taj Mahal is actually an integrated complex of structures. Building began around 1632 and was completed around 1653, and employed thousands of artisans and craftsmen. The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision including Abd ul-Karim Ma'mur Khan, Makramat Khan, and the Persian Ustad Ahmad Lahauri, although Lahauri is generally considered to be the principal designer.

Grand Canyon one of the Wonders of the World

Grand Canyon from South Rim

The Grand Canyon is a steep-sided gorge carved by the Colorado River in the United States in the state of Arizona. It is largely contained within the Grand Canyon National Park — one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

Grand Canyon

Longstanding scientific consensus has been that the canyon was created by the Colorado River over a six million year period. The canyon is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 29 km) and attains a depth of over a mile (1.83 km) (6000 feet). Nearly two billion years of the Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. The "canyon began in the west, followed by another that formed in the east. Eventually, the two broke through and met as a single majestic rent in the earth some six million years ago. [...] The merger apparently occurred where the river today bends to the west, in the area known as the Kaibab Arch."

Grand Canyon Rail RoadBefore European immigration, the area was inhabited by Native Americans who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon ("Ongtupqa" in Hopi language) a holy site and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.

Egyptian pyramids one of the Seven Wonders of the Ancient World

The Egyptian pyramids are ancient pyramid-shaped masonry structures located in Egypt.

There are over 100 pyramids in Egypt. Most were built as tombs for the country's Pharaohs and their consorts during the Old and Middle Kingdom periods.

The earliest known Egyptian pyramid is the Pyramid of Djoser which was built during the third dynasty. This pyramid and its surrounding complex were designed by the architect Imhotep, and are generally considered to be the world's oldest monumental structures constructed of dressed masonry.

The best known Egyptian pyramids are those found at Giza, on the outskirts of Cairo. Several of the Giza pyramids are counted among the largest structures ever built.

The Pyramid of Khufu at Giza is the largest Egyptian pyramid. It is the only one of the Seven Wonders of the Ancient World still in existence.
