A slope between two worlds
Before the staircase, the hill between Piazza di Spagna and Trinità dei Monti was awkward, steep, and hard to use. The long planning story began as early as 1559, gathered momentum after a French bequest in 1660, and finally moved forward after the 1717 design competition. That long delay explains why the finished staircase feels like both infrastructure and diplomacy.
Francesco De Sanctis and the ramps
Francesco De Sanctis built the staircase between 1723 and 1726, using ramps that divide, curve, and reunite instead of marching straight uphill. That movement is the secret. You climb, pause, turn, and see the square differently from each landing, which is why the staircase still feels alive even when you know the view already.
The Barcaccia at the base
The fountain below came first. Pietro Bernini created the Fontana della Barcaccia between 1626 and 1629, turning a low-pressure water problem into a boat that seems to sink gently into the square. Look at it before you climb, and the steps feel less like a staircase alone and more like a stage set around water, stone, and movement.
Restoration and spring azaleas
The steps were fully restored in 1995 and again in 2015-2016, which is why the travertine reads so cleanly in bright light. The softer tradition is seasonal: hundreds of azaleas are placed on the steps from around mid-April to mid-May. If you catch them, the monument briefly becomes a garden, and even hurried locals slow down for a second look.
