The church was designed by Józef Pius Dziekoński, who was responsible for many prominent church buildings in Poland during the early 20th century.
The elevation to minor basilica status in 2004 marked the first such designation in the Roman Catholic Diocese of Łomża.
The structure is built primarily of red brick, which remains exposed on the exterior, characteristic of the Neo-Gothic style popular in the region during the early 1900s.
The church interior contains specific votive elements and decorations that highlight the unique Kurpian folk traditions of the surrounding region.
The Bazylika Rzymskokatolicka pw. Trójcy Przenajświętszej in Myszyniec is a significant Neo-Gothic brick structure located in the heart of the Kurpie region. Constructed between 1909 and 1922 based on the design of architect Józef Pius Dziekoński, the basilica replaced an older wooden church that had stood on the site. It was elevated to the rank of a minor basilica by Pope John Paul II in 2004. The building features a three-aisled layout with a transept and two prominent, high-reaching towers that dominate the local landscape. The interior retains historical altars and stained glass windows reflective of early 20th-century religious craftsmanship. As the spiritual center of the Kurpian community, it serves as a primary venue for regional religious and cultural celebrations. Its location on Plac Rynarzewskiego positions it centrally within the town's administrative and historical core.

Visit during local Kurpian religious festivals to see regional traditional costumes worn by the congregation.
Walk around the perimeter to view the detailed brickwork and the scale of the twin towers from different angles.
Be respectful of ongoing religious services, as the basilica is an active parish church.
Avoid taking photos during active Mass or funerals, as this is a working place of worship for the local community.
Maintain silence, remove hats, and ensure shoulders and knees are covered as this is a consecrated site of worship.
