These collections came from the archives of the former Administration of National Assets of Santiago de Compostela district. They were housed in San Agustín Convent until 1920, when it was occupied by the Jesuits and moved to an attic in the Town Council.
In 1946, the General Directorate for Archives and Libraries of the Ministry of Education authorised the transfer of the collections to the University Historical Archive, after consultation with the General Directorate for Property and Land Taxes, with Salvador Parga Pondal being the archivist.
The chronology of the documentation ranges from the 9th century to the 1930s. Among the most voluminous series are the forums, surveys, rates, censuses, lawsuits, letters patent and rent collections.
