Lincoln Home National Historic Site preserves the Springfield, Illinois home and a historic district where Abraham Lincoln lived from 1844 to 1861, before becoming the 16th President of the United States. The presidential memorial includes the four blocks surrounding the home and a visitor center.
In May of 1844, Abraham and Mary Todd Lincoln purchased a house in Springfield, which they bought for $1500 (hard to beat that price today). The family would have to move again two years later, however, when in 1846 Lincoln was elected to the United States House of Representatives.
