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.”

Charminar (Hindi: चार मीनार, Telugu: చార్ మినార్, Urdu: چار مینار, meaning “Four Towers” or “Mosque of the four minarets”) is one of the most important monuments in the city of Hyderabad, capital of the state of Andhra Pradesh, India. Muhammad Quli Qutb Shah built the monument in 1591 shortly after he had shifted his capital from Golkonda to what now is known as Hyderabad[1]. Legend has it that the building honours a promise Quli Qutb Shah made to Allah. He supposedly had prayed for the end of a plague and vowed that he would build a masjid on that very place. The masjid became popularly known as Charminar because of its four (Farsi char = four) minarets (Minar (Arabic manara) = spire/tower), which possibly honour the first four caliphs of Islam. The actual masjid occupies the top floor of the four-story structure. Madame Blavatsky reports that each of the floors was meant for a separate branch of learning - before the structure was transformed by the imperial British administration into a warehouse for opium and liqueurs. There is a legend that an underground tunnel connects the palace at Golconda to Charminar to give the Qutb Shahi royal family an escape route should they need it during a siege. However, the exact location of the tunnel is unknown.
