The Saidu Sharif Stupa, known as Saidu Sharif I during excavations, holds great significance as a Buddhist sacred site situated near the city of Saidu Sharif in the Swat District of Khyber Pakhtunkhwa, Pakistan. It is nestled at the foothills that separate the Saidu River valley from the Jambil River valley. The sacred area encompasses two terraces constructed on the hill's slope, accessed through a rock cut on the northern side. These terraces include a prominent stupa, surrounded by smaller monuments, as well as a monastery.
The Italian Archaeological Mission initiated excavations at the site in 1963, with the project spanning until 1982, interrupted between 1966 and 1977. The initial excavation campaign focused on the lower terrace, uncovering the main stupa, while the second campaign revealed the upper terrace, housing the monastery.
The lower terrace, referred to as the "Terrace of the Stupas," features a larger main stupa, encompassed by various minor monuments such as stupas, viharas, and columns. The structure of the main stupa, with its square base and a stairway on the northern side, has been preserved up to the first cylindrical body. Fragments of the harmikā (the square railing around the stupa's dome) and the umbrellas that once adorned the stupa have been found near the site. One of the cylindrical bodies of the stupa was adorned with a frieze carved in green schist, while the top corners of the rectangular body were adorned with four columns on pedestals, each topped with a crouched lion figure.
Archaeologists have divided the lifespan of the Saidu Sharif I sanctuary into three periods. In the first period, from approximately 25 BCE to the end of the 1st century CE, the monuments were arranged symmetrically. Over time, the Terrace of the Stupas became more crowded, leading to its expansion during the second and third periods, which occurred between the 2nd-3rd century CE and 4th-5th century CE, respectively. These three construction periods are also evident on the upper terrace, where the monastery underwent expansions followed by a reduction to its original dimensions during the third period, indicating the decline of the entire sacred area.
