He belonged to the dynasty of renowned architects of Italian-Swiss origin and actively participated in the St Petersburg Architects’ Association.

Alexandru Bernardazzi commenced his professional journey in 1850 when he assumed the role of assistant architect at the Bessarabian Road Construction Agency. By 1856, he had earned the title of chief architect of the city of Chisinau, a position he held until 1878. Over the span of twenty-two years, Bernardazzi transformed the city into a capital that closely adhered to European standards and contemporary Western architectural trends.

In 1878, the architect relocated to Odessa, spending the latter half of his life there and contributing significantly to various projects. His passing occurred during a business trip to Fastiv near Kiev in 1907, and in accordance with his wish, he was laid to rest in Chisinau next to his mother.

Bernardazzi left an indelible mark on Chisinau, working on over 30 projects, including the construction of the City Hall, the girls’ gymnasium “Princess N. Dadiani,” the Lutheran parish building, the chapel of the girls’ gymnasium (now the Church of Saint Theodora of Sihla), the noble club, the courthouse, the water towers (with one preserved, now housing the “City Museum”), the Church of Saint Pantelimon, the Armenian Church, and numerous others.

A commemorative plaque adorns the house where the great architect resided until the death of his first wife, located at 23 Sfatul Țării Street. Additionally, a second plaque was installed on the exterior wall of the Church of St. Theodora de la Sihla on A. S.Pushkin.
