At the opposite end of the Colosseum in Rome is Trajan's Market, an ancient and monumental building that was built as an integral part of Trajan's Forum. Many believe that it was one of the largest trading centers in Rome, and was designed based on ancient Roman architecture. The stores were built in multiple layers, some of which still exist today. This historical shrine is considered the third most visited place by tourists in the city, and also attracts all photography lovers around the world.
