This delicate single-domed church, beside the west door of the Assumption Cathedral, was built between 1484 and 1486 in exclusively Russian style. It was the private chapel of the heads of the Church, who tended to be highly suspicious of such people as Italian architects.
Originally an open gallery or porch surrounded the church; it was later removed and the church was connected with the palace for the convenience of the tsars. The interior walls, ceilings and pillars are covered with 17th-century frescoes. It houses an exhibition of 15th- to 17th-century woodcarvings.
