The 30-meter tall Column of Trajan has an interior spiral staircase. How many steps does it have?
Trajan's war on the Dacians (current Romania) was a defining event in his 19-year rule. The conquest yielded a half million pounds of gold and a million pounds of silver. To commemorate the victory, he commissioned a forum that included a large plaza and civic space, two libraries, and the Basilica of Trajan.
