Scupi is the largest Roman town in R. Macedonia and the only one with the status of colony. It is settled at the edge of modern Skopje and occupies an area of 44 hectares inside the fortification walls. The site was excavated in 1928 for the first time and there were many campaigns during the 20th century. The excavations revealed houses from different periods, one of the main streets, bath, theatre and other public buildings. The necropolis of the town was also a subject of the excavations in the past.

In 2005 there were excavations on two points – the Cardo and part of the settlement of the 6th century, which is the last strata of existence at the site.

The cardo connects a couple of public buildings and it has a surface paved with massive stone slabs. The trench was put at the crossroad between the cardo and the decumanus. There are four layers of leveling beneath the paved surface of the streets. The drainage channel was set at the eastern side of the cardo and it has different width from north to south (0.30 – 0.90 m). At several places thеrе are reinforcements having the function of buffers during an inflow of bigger quantity of water.

Three rooms and a well were excavated from the 6th century settlement. One of the rooms is interpreted as a workshop. The seven square stones found inside are thought to be a foundation for a wooden floor. Iron tools and knives were found in the room.
