The Holy Trinity Church in Tykocin is an 18th-century Late Baroque edifice commissioned by Jan Klemens Branicki. It occupies the site of a previous 16th-century wooden church founded by Krzysztof Wiesiołowski. The interior is characterized by extensive frescoes, gilded altars, and preserved historical paintings from the 17th and 18th centuries. The structure features a distinctive facade flanked by two towers, which dominate the town's central square. It serves as an active Roman Catholic parish church under the Archdiocese of Białystok. The architecture highlights the patronage of the powerful Branicki family in the Podlaskie region. Visitors can view the crypts that house the remains of historical figures associated with the town. The church remains a focal point of Tykocin's preserved historical urban layout.
