The main church of the monastery has been dedicated to the Transfiguration of Christ. Its annual feast is celebrated festively on August 6.

The church was designed by architect Ivan Kudrjavzev and represents Northern Russian stone church style. The church was inaugurated in June 5, 1977. Similar white brick churches with only one cupola are typical for example in the areas around Novgorod and Pskov.

Most of the icons in the main church are from the 18th and the 19th centuries and are originally from the old location of the monastery on Valamo (Valaam) island in Lake Ladoga. Older icons or other church items from Valamo monastery than this actuallty don't even exist because the monastery was destroyed several times by fires and wars over the past centuries.

In addition to the icons, also the heavy chandelier made of gilded bronze that weighs 800 kilograms and the grandfather clock from the middle of the 19th century, which originally stood in the altar of the lower church of the main church, come from the original location of the monastery on Valamo (Valaam) island in Lake Ladoga. Also the 14 church bells in the bell tower originate from there.
