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.
