At the far end of the National Mall, the Lincoln Memorial feels even more striking when you walk up the steps and stand where Martin Luther King Jr. gave his defining “I Have a Dream” speech. Inside, Lincoln’s 19-foot statue looks out over the long Reflecting Pool toward the Washington Monument. Go at sunrise or after dark if you want a quieter moment — the view’s completely different depending on the time of day.

This majestic mausoleum dedicated to the 'Father of Modern Tunisia' Habib Bourguiba is decked out from top to bottom with white marble and decorative touches of emerald green, making it gleam in the hot sun of Monastir. The two towers poised on either side of the entrance to the tomb resemble the minarets of a typical Maghreb mosque. Indeed, most of the architecture that was designed by French architect Olivier Clement Cacoub bears a strong resemblance to traditional Islamic places of worship. Inside the mausoleum lies the Tunisian president of the 1960s, encased in an ornate marble sarcophagus which can be viewed up close on the ground floor or from above by accessing the balcony through an unassuming door to the right of the main entrance. Although it is free to enter the mausoleum, some may prefer to gain further insight into the history of the building by booking a tour from one of the licensed tour operators in the main city. It is inadvisable to hire the services of those guides operating within or beside the grounds of the mausoleum as most are unqualified. Opening times may vary and if the main entrance is closed, visitors can enter through a separate entrance on the other side of the building.
