Trajan’s Column, Rome
Trajan’s column, you can view it for free in Rome, no tickets required. It is in the same area as Colosseum and Forum.
The column was erected in honor of Trajan. The statue at the top is of St. Peter’s; it was installed there in 16th century. The column made entirely of marble depicts the significant stories of Emperor Trajan’s victory over Dacians. It is a hollow column and there is a spiral stair of 185 steps that gives access to the platform above. Entrance to this was not possible even with a fees when I visited last April.
