The Edifice of the Sun is the most stunning structure of the Golestan Palace. The idea of building a tall structure came to Nasser ol Din Shah who wanted a structure from which he could enjoy panoramic views of the city. Designed by Moayer ol Mamalek, the construction on this building began in 1865 and was completed two years later. The architect of this palace was Ali Mohammad Kashi. The building has two identical towers. The exterior views have multiple arches, intricate tile work and ornate windows.
Golestan Palace is actually the former royal Qajar complex , located at Iran's capital city, Tehran. It is one of the oldest historic monuments in Tehran, and also has a World Heritage Status. This Palace also belongs to a group of royal buildings that were once enclosed within the mud-thatched walls of Tehran's arg (citadel). This palace also consists of gardens, royal buildings and varied collections of Iranian crafts from the 18th and 19th centuries.
