â Samwell Tarly talks about the Wall. The Wall is a colossal fortification which stretches for 100 leagues (300 miles) along the northern border of the Seven Kingdoms, defending the realm from the wildlings who live beyond. The Wall is reported to be over 700 feet tall and is made of solid ice.
Opened in 1910, the National Museum of Natural History (NMNH) is part of the Smithsonian Institution, the worldâs preeminent museum and research complex.
In March 2016, Smithsonian officials said the project's cost had risen to $600 million. In late June 2016, Smithsonian officials projected the museum's renovation to cost $1 billion. This included $676 million for construction, $50 million to build new storage space, and $250 million for new exhibits.
