A monument above the common grave of Russian warriors killed in the battle of Poltava was opened on June 27th in presence the Emperor Alexander III. However, the heavy granite cross started to sink. In 1906 a decision to open the common grave of Russian warriors, reinforce the foundation of the memorial and built an inner chapel with spherical vault was made.

It was built by design of architect Nosov and while construction was under way a few photos of open grave were taken. Later these photographs were discovered in the War Archives in Stockholm. The grave chapel had a small window and its entrance faced north. There were a few marble plaques with a lists of Russian regiments that participated the battle of Poltava, colours and laurel wreath’ in it. The inner walls and vault were painted by artist Sokol. St. Peter and Paul grave chapel was consecrated to God on September 3rd 1907. In the 1930s a pig-breeding research institute was founded near the common grave. Shortly the grave chapel was turned into fuel and chemicals storage by the institute’s director. This act caused the destruction of the ventilation system and wall paintings. The walls then began to dampen and disintegrate. After WWII the grave chapel has been repaired several times but its unique interior was lost for forever. Later the church was turned into simple mournful hall, which only decoration was a grave stone. Now this chapel is in poor condition and closed for visitors.
