Latsis and the Hellenic Cancer Society, for the transfer of the unit to The Hellenic Cancer Society’s facilities at the Pylaia Guesthouse.

In 1985, Theagenio becomes a public entity and is incorporated into the N.H.S. Shortly afterward, the Centre of Preventive Medicine is organized and in 2001 it is incorporated into the A’ Regional Health and Welfare System.

In 1975 the Nursing wing is opened.

In 1957 it was converted into a model Special Cancer Institute and in 1963 the first building was inaugurated with the Director-General Professor Alexandros Simeonidis.

In 1945, Theagenio hosted the University Pediatric Clinic – until 1955 when it was transferred to AHEPA.

In 1940-1941 Theagenio is again converted into a Military Hospital.

During 1923-1925 Theagenio grants its facilities to the Charitable Society of American Ladies of the Red Cross, for the establishment of a Maternity Hospital and Pediatric Clinic for refugees.

In 1912, with the liberation of Thessaloniki, Theagenio is converted into a military hospital.(1912-1914)

In 1909 the Surgical Wing is built and equipped with bequests from Dimitrios Ioannidis.

In 1895 the new Hospital is completed, built to the designs of Ernest Chiller on the site of the present hospital.

The building was completely destroyed in the great fire of 1890 and began to be rebuilt in 1891-92 with the compensations from insurance companies and the contribution of major benefactors (such as Andreas Syngros).

The Hospital is built on the same site in the area of the Metropolis and begins to operate in 1866. It was originally called Charisison and was later renamed Theagenion (when Dimitrios, the brother of Theagenis Harisis, founded the nursing home named Harrision). Many benefactors of Thessaloniki support the Hospital with donations and bequests.

In 1863 Theagenes Charisis left his estate to the Greek Community in his will for the creation of a modern
Hospital.

In 1840 the English consul refers to the Greek Hospital of Thessaloniki and describes the poor condition in which it was despite the efforts of the Greek Community.

In 1823 the Greek Community, in dire straits after the Greek Revolution, is forced to sell the new Hospital building in order to be able to maintain its older Hospital, which continues to operate.

In 1781 the Venetian consul describes an epidemic of plague in Thessaloniki and refers to the second main hospital of the Hellenic Community in the “plague house”.

In 1754 the Hellenic Community asks and receives help from France through its consul, for repairs and expansion of the Hospital.

In the middle of the 17th century, by the Turkish traveler Evlija Tselebi, there is the first reference to the existence of a hospital of the Greek community in Thessaloniki.
