One of the most iconic sites in the world, the Pyramids of Giza, just outside Cairo, are a surreal sight rising from the barren desert landscape. Standing guard nearby, and almost as impressive, is the Sphinx, gazing blankly out over the land.

The pyramids were built as tombs for the Pharaohs, the largest of which was constructed between 2560 and 2540 BC. To put their age in perspective, they were already more than 2,600 years old when the Colosseum in Rome was being built. Today, these giant monuments are the sole surviving member of the Seven Wonders of the Ancient World.

Borobudur is one of the most important Buddhist sites in the world and certainly one of Indonesia's most famous landmarks. Set in lush, tropical surroundings, with mountains and volcanoes rising in the distance, the site is visually stunning and soothingly peaceful.

Located on the island of Java, near Yogyakarta, this massive temple complex was constructed in the 700s, but two to three hundred years later, the site was abandoned, possibly due to volcanic eruptions in the area, and went relatively undisturbed for centuries. The site was uncovered in the 1800s by the British and later restored. Today, it is one of the most important tourist attractions in Indonesia.
