A stairway, staircase, stairwell, flight of stairs, or simply stairs is a construction designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles.
Special types of stairs include escalators and ladders. Some alternatives to stairs are elevators (UK: lifts), stairlifts and inclined moving walkways as well as stationary inclined sidewalks (UK: pavements).
The Vatican Museums (Italian: Musei Vaticani), located inside the Vatican City State, are among the greatest museums in the world, since they display works from the immense collection built up by the Roman Catholic Church throughout the centuries including some of the most renowned classical sculptures and most important masterpieces of Renaissance art in the world.
Pope Julius II founded the museums in the early 16th century. The Sistine Chapel with its ceiling decorated by Michelangelo and the Stanze della Segnatura decorated by Raphael are on the visitor route through the Vatican Museums. They were visited by 4,310,083 people in the year 2007. The Vatican Museums broke attendance records in 2011 with just over 5 million people.
