Pietro Arrigoni (August 9, 1856 – 1940) was an Italian architect from Milan, mostly known for his work in the city of Thessaloniki in northern Greece.
He studied architecture at the Accademia Reale di Belle Arti, where he won a prize for his Palazzo design.
[2] Along with the works of Alexandre Vallaury, Arrigoni's project introduced new construction technologies and helped disseminate the use of concrete and iron structures in the Ottoman Empire.
He temporarily left the city due to the Italo-Turkish War and returned in 1912.
In 1921 he founded an architectural office with his son, and between 1923 and 1926 he designed a settlement for Greek refugees.
