The Sponeck castle was built in the late 13th century to the site of late Roman fort (built by Emperor Valentinian I around 365 AD). The castle was destroyed in the Thirty Years War. After several changes of ownership the painter Hans Adolf Buhler acquired it in 1917, rebuilt and set up a studio in the former residential tower. After the painter's death in 1951 the castle was owned by the family. Today the stone wall and two corner towers are preserved of an original Roman fort.
The Lincoln Memorial is an American national monument built to honor the 16th President of the United States, Abraham Lincoln. It is located on the western end of the National Mall in Washington, D.C., across from the Washington Monument. The architect was Henry Bacon and the designer of the primary statue was Daniel Chester French.
Dedicated in 1922, it is one of several monuments built to honor an American president. It has always been a major tourist attraction and since the 1930s has been a symbolic center focused on race relations.
The building is in the form of a Greek Doric temple and contains a large seated sculpture of Abraham Lincoln and inscriptions of two well-known speeches by Lincoln, 'The Gettysburg Address' and his 'Second Inaugural Address'. The memorial has been the site of many famous speeches, including Martin Luther King's 'I Have a Dream' speech, delivered on August 28, 1963, during the rally at the end of the March on Washington for Jobs and Freedom.
Since 2010, approximately 6 million people visit the memorial annually.
