The Archaeological Museum, also known as “The Mosaic,” was discovered in 1968 by archaeologist Dhimosten Budina, dating back to the Late Antiquity period. Found during construction of the old Post Telegraph Telephone building, the mosaic showcases a 3rd-century design with intricate stonework measuring 12.8 m by 11m.

In the 2000s, additional sections of the monument were uncovered during drainage work, indicating that this site may have been transformed into a religious basilica in the 6th century A.D. Due to modern developments, the complete structure, original layout, and surrounding areas are not fully known. However, the mosaic’s intricate geometric patterns and design hints at its historic roots, possibly altered by later artistic concepts as its use evolved over time.

At the time of its discovery, the monument showed considerable damage, especially in the southwestern part. In 2010, restoration efforts by experts from the Institute of Cultural Monuments and the University of Bologna helped restore its former splendor. Today, it is accessible to the public as part of the museum triangle in Saranda, along with the Museum of Tradition and the Saranda Art Gallery.
