The entire site covers around 135 hectares (330 acres), mostly made up of the outer city.
The high mound covers about 18 hectares (44 acres) and rises to a height of 25 metres (82 ft), with 5 sub-mounds.
The high mound is surrounded by a mudbrick city wall that was roughly 8 metres (26 ft) wide and 7 metres (23 ft) high.

Important excavated structures include the royal palace of Tupkish, an associated necromantic underground structure (Abi), a monumental temple terrace with a plaza in front and a temple at the top, residential areas, burial areas, and the inner and outer city walls.

Soundings at the site were first made by Max Mallowan during his survey of the area.
Agatha Christie, his wife, wrote that they chose not to continue at the site because it seemed to have Roman material.
No trace of Roman occupation levels have been found in later excavations, however.
Mallowan went on to excavate Chagar Bazar, another site to the south of Mozan/Urkesh.
Excavations at Tell Mozan began in 1984 and have been conducted for at least 17 seasons up to the present time.
The work has been led by Giorgio Buccellati of UCLA and Marilyn Kelly-Buccellati of California State University, Los Angeles.

The 2007 season was primarily dedicated to working on publication material, primarily excavation units A16, J1, J3 and J4.
A small sounding was done in J1 to clarify the transition between Mittani and Khabur.
The excavations have been assisted at various times by other groups including the German Archaeological Institute.

The excavations at Tell Mozan are known for the project's interest in pursuing the uses of technology in an archaeological context.
The main focus is on the 'Global Record', a method of documentation that combines journal entries into a hypertext based output.
This system marries the advantages of both the database and prose type approaches, in that elements are individually linked across both stratigraphy and typology, and yet remain tied in a more synthetic whole through the narrative of the archaeological record.
Another focal point of research at the site is the application of conservation.

The mud brick architecture which comprises the majority of the structures found to date has been preserved over the years though an innovative system.
This system protects the monument while still allowing a detailed inspection of the primary document as originally unearthed.
The same system affords an overview of the architectural volumes as perceived by the ancients.
A sizeable lab in the field research facility allows the conservators to give the best possible on-site care while interacting with the excavations.

Special emphasis is placed on documenting the concrete types of contact which are observed in the ground.
This is done with great detail at the level of each individual feature.
From this evidence is automatically derived a complete depositional history of all elements in contact.
The strata are conceived as segments of this continuum in which a single depositional moment can be reconstructed.
The phases are periods that are culturally identifiable on the basis of typological and functional analysis.
Horizons are the broad chronological subdivisions based on comparative material and as they can be linked to the general historical understanding.

One of the most important fixed points of reference for chronology are impressions on door sealings of the seal of Tar'am-Agade, the daughter of Naram-Sin, which because of stratigraphy can be firmly linked to phase 3 of the AP palace occupation.

Finds from the excavations at Tell Mozan are on display in the Deir ez-Zor Museum.
