The archive consists of

• a letter book from the years 1856-1861
• correspondence from the years 1826-1860
• a register of deeds from the period 1854-1867
• a register of arrivals and departures of ships from Alexandretta from the years 1827-1829.
  The proconsulate of Alexandretta was under the direction of Aleppo from 1827 to 1829 and again from 1849 onwards.

The documentation, organised into annual files, probably arranged at the time of their delivery and/or arrival at the Historical Diplomatic Archive of the Ministry of Foreign Affairs, is heterogeneous, although it consists mainly of received correspondence.
In order to provide more information to those consulting this small archive, an attempt has been made to list the recurring correspondents.

The following have been identified

1) institutional correspondents:

• the officers of the Legation in Constantinople
• consular officers stationed in Beirut (the proconsulate of Aleppo depended on that Consulate)
• local interlocutors (consuls of other nations, for example)
• other Sardinian consuls in the Levant

.
2) other interlocutors, often nationals residing in the area

The list is not to be considered exhaustive.
