The Sigiriya terrace gardens gradually rise up from the boulder gardens to meet the base of Sigiriya rock. It was designed to provide a series of views that gradually rose up with the natural contour of the Sigiriya foothill. Boulder arch No.1 is located in this garden. The architect has created the stairway through this natural boulder arch to create an effect. The terraces were created with brick and marble. In between the boulders, one can see traces of brickwork terraces. A marble flight of steps leads up through the Sigiriya terrace gardens to the Sigiriya lion rock ancient stairway.
