The Roman Catholic Cathedral of St. Joseph the Worker in Piatra-Neamț was built in 1895 and underwent numerous renovations between 1936 and 1939. The church has completely changed its appearance since 2012, following an extensive modernization process.

The first Catholic families settled here in the 17th century. Over time, the number of Catholics grew, so that in 1996 a second parish center was established, dedicated to St. Thérèse of the Child Jesus.

The arrival of the first Catholic believers in this city was facilitated by the commercial and craft activities carried out here. 

The subsequent economic development of the Bistriţa Valley region, especially in the 18th century, led to the creation of a new Catholic community in Piatra Neamţ. The report of February 19, 1765, by the prefect of the Mission in Moldova, Father Iosif Oviller, mentions the need to appoint a priest for this community.

In 1850, there was a French colony in Piatra Neamţ, with 185 inhabitants and its own priest, Father Francisc Craimer, who also served as parish priest. There is also an important documentary relic (a stamp) attesting to the existence of a parish in Piatra Neamţ.

The cathedral was built in 1895. The current church is the result of the modernization and beautification of the church around 1900. Between 1936 and 1939, it underwent numerous renovations, and at the same time (1939), the parish house was built. The church completely changed its appearance in 2012, after an extensive modernization process.

Saint Joseph, the caring father of Jesus, was proposed by Pope Pius XII in 1955 as the patron saint of workers. 

Saint Joseph the Worker is proposed today as a model because he excels in his work. In his case, work was a means of human fulfillment. He made a name for himself—a "carpenter"—through his work. He earned the respect of those around him, work being for him a path to growth in identity and dignity.
