A small church that forms part of a complex making up Russia's emblematic Saint Basil's Cathedral was previewed on Friday after its interior had been revamped following renovation works, as documented by an epa-efe photojournalist.

The Russian Historical Museum presented the renovated interiors of the little church of St. John the Blissful that is part of St Basil's Cathedral, officially named the Cathedral of the Intercession of the Most Holy Theotokos on the Moat.

The monument is also known as the Cathedral of Vasily the Blessed or the Pokrovsky Cathedral and consists of nine individual churches.

The cathedral was built by Russian architects from 1555-1561 under Ivan the Terrible's orders and soon became a landmark of Moscow's Red Square.

It was closed over the years of the Soviet Empire and now experts of the State Historical Museum are progressively opening different parts of the church complex.

The side altar of the St. John the Blissful church is one of such parts that has undergone renovations.

The church will once again open for religious services.
