The Santi Angeli House in Sassari, built in 1919 on a large area adjacent to Umberto Avenue, was established on the initiative of Don Nicolò Sussarello, the first benefactor who wanted to create a small shelter for underprivileged children. The vast complex, currently covering nearly one hectare, was made possible by several donations, including that of teacher Rosina Chessa in 1963. Over the years many children have been welcomed, educated, comforted, professionally trained accompanied until adulthood.
The Work was governed from its foundation, and for a number of years, by the Damine di Carità of St. Vincent de Paul. From 1928 the responsibility was entrusted to the Missionary Congregation of the Daughters of Jesus Crucified (founded by Father Salvatore Vico) of Tempio Pausania. The House has been closed for more than a decade. As a result of the complete demolition of the existing buildings, a modern and functional complex was created, equipped with rooms, study and relaxation rooms, an auditorium for conferences, a chapel, the Lourdes Grotto (the work of Monsignor Arcangelo Mazzotti in the 1950s), as well as a vast park.
