In the course of the ongoing research of the Malsky Monastery in the Pskov region, the specialists of the "ASM Group" discovered a laid entrance to the subclet of the Quartet of the Church of the Nativity of Christ.

The stone vault, steps and wooden deck of the doorway are only the first discoveries on the historical volumes of the temple laid down in later times. Research is ongoing and will likely lead to the discovery of previously unknown underground volumes and building structures of the oldest part of the church.
