Rome was the capital of the Roman Empire. During this time many monuments were created that the world had never seen before. Some of these are still standing like the Colosseum or the Pantheon. However, many have crumbled.
When you visit Rome, you will surely see many archeological remains. No visit to Rome is complete without a visit to the Forum Romanum or Palatine Hill. The problem many visitors face is that not much is explained at these sites. Even at the Colosseum, there are no signs that explain the building. This can be very frustrating.
You are standing in the Forum Romanum, the heart of the Roman Empire, and all you see is rubble and broken stones. Believe me, your visit will be much more interesting and exciting if you know what the remains of the buildings were. If you know you are looking at the Senate building where decisions were taken that influenced history, your whole visit becomes much more interesting and profound.
