According to Anna Lewkowska, Jacek Lewkowski and Wojciech Walczak, the Holy Trinity Cemetery (originally built in 1662, the present one dates back to 1812) in Zabłocie contains a cemetery with six preserved tombstones. The oldest, from 1829, belongs to Antonina Poplawska and bears the inscription: "TO THE CORPSE / OF ANTONINA Z PRZYBYTKÓW / POPŁAWSKA / ZAMRŁY W 1829". The aforementioned authors report that "a rectangular marble plaque in memory of Krystyna Nowicka (d. 1834) is set into the church wall, on the left side. The inscription on the plaque is an artistic composition of lettering, made in the engraving workshop of Jakub Rosiński of Vilnius." The cemetery is maintained in good condition.
