Narew Jewish Cemetery

The synagogue in Orla was designed in the Baroque style in the middle of the 17th century with a building plan for nine bays and a vaulted ceiling. The synagogue has been rebuilt and remodeled many times. In the early 19th century, two wooden staircases were added to the women's gallery and the façade of the synagogue received a classical design. The wooden Torah ark, the murals on the eastern wall of the prayer hall, and its columns are original to the time of the construction of the synagogue. The murals on the eastern wall were connected to the wood and stucco ark and are partially preserved. The decoration theme includes peacocks and other birds, and garlands and grapevines. The murals in the arch above the entrance with 'the four animals' motif were painted in the 1920s.

The St. Wojciech Church, formerly the Evangelical Church of St. John the Baptist, is a Roman Catholic brick church built in 1908-1912 in the neo-Romanesque style. In 2013, a fire seriously damaged the church. The wooden structure of the bell tower burned down completely and collapsed.

The Cathedral Basilica of the Assumption of the Blessed Virgin Mary is composed of two religious buildings connected to each other: the old (early seventeenth century) and the new (early twentieth century).
