On Sunday, October 3, 1915, Anna Kahan described in the diary her return from Pińsk. When the train was pulling in to the station, from afar she saw the towers of the new church and then the dome of the Orthodox Church. After leaving the train, she also noticed that there were no longer signboards with inscriptions in two languages: Russian and Polish.

The Orthodox Church stood as before, but the Russians were no longer there. The temple was built at the intersection of Ogrodowa Street (currently Sienkiewicz Street) and Alejowa Street (currently Kiliński Street). In 1870, the Orthodox Church of the Holy Spirit was consecrated. Today, it is a Roman Catholic Garrison Church of the Sacred Heart of Jesus and is located at the intersection of Sienkiewicz Street and Kiliński Street, on Tysiąclecia Square.

After Poland regained its independence in 1918, an Orthodox church was perceived as a legacy of the partitions. By the Decree of December 16, 1918 and the Act of December 17, 1920, church property in the former Congress Kingdom was confiscated and placed under the compulsory supervision of the State. The symbol of the transformation was the demolition of a Russian Orthodox Cathedral in Warsaw and rebuilding of the Orthodox Church in Siedlce.

A thorough rebuilding of the church began on the 10^th anniversary of regaining independence by Poland. For that reason, a social committee was appointed to oversee the implementation of the project. The rebuilding took four years. The building was deprived of some architectural details, and undoubtedly lost its beauty. From a bird’s eye view, it looks as if a screen covered the shape of the former Orthodox Church roof.

We go further down Sienkiewicz Street. On the left, we see the school building. In Anna Kahan’s time, directly in front of this building was the school of Jadwiga Barszczewska.
