He participated in the design and construction of many buildings in Bessarabia such as School of Lutheran parish, Greek Church, the Passenger’s Building South-Western Railway, the Palace of Prince Manuk Bey in Gancheshty and etc. Bernardazzi took active part in paving many streets in Chișinău and created the cast-iron rail in the city garden. After arriving in Odessa in 1878, Alexander Bernardazzi continued to design many stately and imposing buildings in Bessarabia, which became the best examples of European architecture.
