They are made of travertine quarried near Tivoli. In their upper part, there are large terraces from which you can admire the surroundings. On top of the stairs, the church of the Holy Trinity is located. The church is highlighted by the symbolism contained in the shape of the staircase. A pyramid of three terraces (a reference to the Holy Trinity) spreads out like an ocean wave. The wavy lines were intended to emphasize movement as a symbol of life. The lowest and the widest part of the composition was meant to symbolize the power of the Holy Spirit. The monumental staircase is decorated with numerous garden terraces adorned with flowers in spring and summer.
