The head of the General Directorate of Antiquities and Museums, Ahmad Deeb, said Friday that the materials include 69 antiquities and eight mosaics that were retrieved from Lebanon.
Thousands of antiquities have been looted or smuggled outside Syria since its crisis began in March 2011.
In December, UNESCO called on the United Nations to curb multi-billion dollar artifact trafficking from Syria and Iraq, where Islamic State group fighters destroyed archaeological sites.
Deeb said today that authorities have closed some museums after taking antiquities to safe areas for fear they might be looted or destroyed.
