Delhi is often called the "City of Crossroads," the "Heart of Empires," and the "Capital of Seven Cities." The city is known for its unique concentration of historical monuments from different eras, three of which (Qutub Minar, the Red Fort, and Humayun`s Tomb) have been included in the UNESCO World Heritage List since the 1990s. Today, Delhi ranks among the top ten most visited tourist destinations in India, welcoming millions of guests each year who come seeking contrasts, flavors, and history.
