The Roman Amphitheater in Trier is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site. The arena, built in the 2nd century A.D. for cruel games with gladiators and animals, had a seating capacity of about 20,000. When you enter the premises you walk through the ruins of the entrance gate. This was used as a quarry in the Middle Ages. The arena itself is surrounded by a protecting wall with openings for animal cages. Underneath the arena is a vast cellar where, in Roman times, prisoners sentenced to death were kept alongside exotic wild animals like African lions or Asian tigers.References:
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.
