As an art historian, I spent much of my time in Iran visiting architectural monuments and museums. Below are photos from the Malek Museum, the National Museum of Iran and Golestan Palace.
The Malik Museum, founded by Haj Hossein Aqa Malek, is the first private museum in Iran. The collection is best known for its manuscripts, but includes paintings, ceramics, lacquerware, textiles and more. There is a gorgeous well-equipped and well-lit library and education center for children. When I visited there was a small, but beautifully curated show on medieval cartography.
The National Museum of Iran is housed in two separate buildings dedicated to Pre-Islamic and Islamic art. I spent a great deal of time in both, but I was especially impressed with the renovations and display in the Islamic wing. The Seljuk collection was phenomenal.
Golestan Palace was the Royal Qajar residence in Tehran (a Persian Dynasty reigning from 1785 to 1925). The complex is constructed around a sprawling garden filled with fountains. Most of the buildings have a set of rooms that have been turned into a museum, either displaying period interiors or an art collection.
