In 1907, in Omsk, to express the patriotic feelings of the residents towards the monarch and to celebrate a joyful event in the royal family, a stone chapel was built near the Iron Bridge. It was dedicated to the birth of the heir to the throne, Alexei Nikolaevich.

At a time when the country was suffering from the pain of defeat in the Russo-Japanese War, it was decided that the income from the sale of candles, after deducting the expenses for maintaining the chapel, would be directed to help the families of those who died in this war.

The chapel was named in honor of Seraphim of Sarov and the heir Tsarevich Alexei. Inside, boards with the names of those who fell in the war were installed, and the eternal lamp that burned in the chapel became a prototype of the modern Eternal Flame. It is believed that the architect of the chapel was A.D. Kryachkov, although other sources suggest it was von Hohen, who used motifs of Yaroslavl architecture in the design.

In 1928, the chapel was demolished by the decision of the presidium of the Omsk City Council, considering it to have no artistic value. In 1994, the chapel was restored according to the project of artist V.A. Desyatov.
