14 feb 1914 anni - the first stone of the Lincoln Memorial is put into place

Descrizione:

Abraham Lincoln changed a lot of things we should be super thankful for that kin of leader. To show that we were thankful for what he has done for our country and how it impacted our lives. In 1911 it all started with an idea . In 1913 the lawmakers approved the commission's designs and location. The work was divided into two parts, a sub-, and an upper-foundation. Because the memorial was to be built on drained and filled land, extra care had to be taken with the foundation for such a massive structure. The sub-foundation is made up of 122 solid, poured concrete piers with steel reinforcing rods anchored in bedrock. The upper foundation is a second series of piers resting on the primary columns. The top piers are all joined together by poured concrete arches that form the floor of the memorial, later covered with a sheathing of marble.
