In the centre of Wojnowo there is a village molennaya (house of prayers) built in 1921 (other historical sources claim it was 1922 or 1923). Built of red brick with a perpendicular roof, it resembles more of an Evangelical church. It still hosts services.
In 1930, on the 100th anniversary of the Old Believers settlement in Masuria, a ceremony was organized in Wojnowo. As part of it a new school was built and a memorial stone was erected. Currently, a board showing the history of the Philippians (Old Believers) in Wojnowo has been hung on the school wall. The memorial stone has been renovated.
