Here’s an interior view of the famous Leaning Tower of Pisa you don’t typically see. Taken by Salena Lettera of The Daily Rant, we see the worn marble steps that lead to the top of the tower.

The Leaning Tower of Pisa is a freestanding bell tower whose tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure’s weight. Completed in 1372 after 199 years of construction, the height of the tower is 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side.

Made of marble and stone, it is 296 steps to the top of the tower and there are seven total bells [source]. You can read more about Salena’s journey to the top on her blog.
