were stored at the ''Conservatoria'', located opposite the Casa del Commun Tesoro. This building was demolished in the 1780s to make way for the
Bibliotheca. The Treasury was headed by a Grand Commander, who was assisted by two Procurators of the Treasury, a Procurator of the Grand Master, a Conventual Conservator and a Secretary. The latter resided in an apartment within the Casa del Commun Tesoro.
In 1708, Malta's first proper postal service was established, and a room within the Casa del Commun Tesoro became the island's first
post office. The building continued to house the Packet Office until around 1841, when it was transferred to the
Banca Giuratale. On 1 April 1849, the Island Post Office was also transferred from the Casa del Commun Tesoro to the Banca Giuratale, which later became known as the General Post Office.
In the early 19th century, the British used the building for a number of public offices, including the Chief Secretary's Office, the office of the Collector of Land Revenue and the Government Treasury.

English poet and writer
Samuel Taylor Coleridge worked inside the building between 1804 and 1805. A plaque on the façade of the building was attached by
Giovanni Bonello in the commemoration of Coleridge. It was converted into a
hotel in the late 19th century, known as the Grand Hotel. At one point, part of the building also housed the second
cinema to open in Malta, which was called the Grande Cinematografo or the Salinos Cinema. Since the early 20th century, the building has housed the

The building was severely damaged by aerial bombardment in
World War II. In 1942, the grand stairway was destroyed after a bomb fell in the building's courtyard, but it was later rebuilt.
At this point the building was redesigned, with several modifications, by Francesco Sammut.
The building is scheduled as a Grade 1 national monument by the
Malta Environment and Planning Authority.
