Colonna di Traiano
Lonely Planet review
Set among the ruins of Trajan's Forum, Trajan's column (AD 113) is adorned with painfully intricate reliefs depicting the victories over the Dacians (from modern-day Romania). It became Trajan's tomb, with his ashes buried underneath and a golden statue resting on top (later replaced by one of St Peter by Pope Sixtus V). Casts of the column at Museo della Civiltà Romana will spare you the sore neck.
