View from the Washington Monument This photograph was taken from the top of the <a href="http://mallhistory.org/items/show/36">Washington Monument</a> in 1942. The <a href="http://mallhistory.org/items/show/52">Smithsonian Castle</a> and <a href="http://mallhistory.org/items/show/55">National Museum of Natural History</a> are visible in the middle of the picture. <a href="http://mallhistory.org/items/show/364">In the 1930s, the trees on the Mall were removed and rows of American elms were planted</a>, per the <a href="http://mallhistory.org/items/show/350">McMillan Plan</a> for the Mall proposed in 1901. This picture clearly shows the rows of young trees stretching on either side of the open middle section of the Mall.
