The original church, known as the Old Church, was built in the early 17th century by Krzysztof Wiesiołowski.
The neo-Gothic expansion was initially denied construction permits by Tsarist Russian authorities, forcing architects to design the new structure as a massive extension of the existing church rather than a separate building.
The two buildings are physically connected, creating a unique hybrid layout that integrates two different architectural eras.
The cathedral's design was heavily influenced by the Vistula Gothic style, which was popular in 19th-century Poland.
The interior of the new basilica features a three-nave hall layout typical of the neo-Gothic movement.
During World War II, the cathedral narrowly escaped significant damage, preserving most of its original 20th-century interior fixtures.
The Cathedral Basilica of the Assumption of the Blessed Virgin Mary in Białystok is a complex consisting of a neo-Gothic cathedral built between 1900 and 1905 and the original smaller church constructed between 1617 and 1625. The site serves as the seat of the Roman Catholic Archdiocese of Białystok. Its architectural history is notable for the construction of the large neo-Gothic building directly attached to the south side of the smaller, older church. The older structure is a prime example of late Renaissance architecture in the Podlaskie region. The complex features dual steeples reaching 75 meters in height. It was elevated to the status of a minor basilica in 1985 by Pope John Paul II.
