"Vitaliano Poselli was born on June 7, 1838 in Castiglione, Sicily. Soon after his graduation, he moved to Rome, where he probably started his studies in architecture. There he was offered his first job in 1867 by a catholic priest, named Don Bosco. It concerned the erection of the church of Santo Stefano in Istanbul.
Poselli after living for some years in the Ottoman capital, was sent in 1886 to Thessaloniki by the Ottoman government in order to build the "ldadie" school of the city. In 1888 he married Luisa Sanchioni from Perugia and settled in Thessaloniki. He continued collaborating with the Ottoman authorities and designed the most important public buildings of the city. At the same time, foreign agencies and missions as well as wealthy traders and bankers entrusted him with the creation of several communal, commercial and private buildings. He was honoured for his work by the Sultan Abdul Hamid 11, Vittorio Emanuele II and the Catholic church.
Vitaliano Poselli died in 1918. One of his 8 children and several of his grand-children are still living in Thessaloniki. Their testimony was of a great help with my further research."
"Built in 1902 for the Deunmeh community4, Yeni Cami is the first identified work of Vitaliano Poselli in Thessaloniki. In 1925, after the departure of all Muslims, the mosque was slightly modified in order to house the newly established archaeological museum of the city. At present it is used by the Municipality as an exhibition hall."
