Gold bars from the vault of a bank and Swiss one franc coins are seen in this illustration picture taken in Zurich November 20, 2014. The “Save our Swiss gold” proposal, spearheaded by the right-wing Swiss People's Party (SVP), aims to ban the central bank from offloading its reserves and oblige it to hold at least 20 percent of its assets in gold. The referendum is scheduled for November 30. The SVP argues it would secure a stable Swiss franc. (Photo by Arnd Wiegmann/Reuters)

Hawa Mahal, which translates as the Palace of Winds, was built in 1799 by Maharaja Sawai Pratap Singh. The design of the palace was created by Shreyansh Jain to resemble the crown of Krishna. The design of this unique five-story building is akin to a honeycomb. The main purpose of this building was to allow royal ladies to watch the street below while remaining unseen, since during those times they had a strict code of dressing, which meant covering their faces. The palace was designed to produce the Venturi effect, which created natural air conditioning and kept the interior relatively cool during hot summers.

Labourers walk near trucks loaded with logs, which are trapped on a muddy road, near an unreserved forest in the village of Igbatoro, southwest Nigeria, August 28, 2014. Wood, a form of biomass, is the sole source of energy for hundreds of millions of Africans who lack access to modern sources of power, and logging, both legal and illegal, remains a lucrative business that has contributed to the rapid shrinking of Africa's rainforests and woodlands.
