| The Trinity Cathedral (1422 – 1423) |   
|  In 1422, the solemn act of  canonization of  Sergius took place. In 1422 – 1423, “in praise of Sergius” the monumental white-stone Trinity Cathedral was built at the place of the wooden Trinity Church.  It became a compositional center of the developing Monastery ensemble. The Cathedral is a rare monument of  Early Moscow architecture. The monument is made of white stone. It is square in plan. It has three semi-circular apses at the East and four pillars supporting the drum and cupola inside. The walls  with narrow  windows are unusually inclined to the center enhancing the impression of  monumentality and  balance of the Cathedral  and, at the same time,  its rising skyward. The facades are divided by vertical flat pylons. The walls, apses and cupola drum are decorated with a carved white-stone  horizontal  frieze with  a  cross and floral pattern. The walls are crowned with  keel zakomars.  The diagonal kokoshniks – decorative imitations of  zakomars -  are overtopped with a massive  tower-like drum which is  slightly removed to the east. The drum is crowned with a helmet-shaped cupola. The picturesque arrangement of  the  shapes is  a characteristic feature of the Trinity Cathedral. The Cathedral is not large, but inside it looks higher. The impression is  achieved due to  systematic  optical corrections. 
 
  The Cathedral preserves one of the first developed iconostases of the 15th century including 42 icons created by Andrei Rublev and painters of his team. The famous “Trinity”,  which is displayed in the Tretyakov Gallery now, was painted by Andrei Rublev for this iconostasis. Its place to the right of the Royal Doors is occupied by a replica painted by N.A. Baranov. In the south-eastern corner of the Cathedral there is a silver tomb with a chased pattern and a text from “The Life of St. Sergius”. It is the shrine with the relics of  Sergius of Radonezh. It was made at the end of the 16th century by  a group of 14 silversmiths including Russian and foreign craftsmen. At the 18th century, a silver ciborium was installed on four pillars over the ciborium. It was made by David Priff to the design of  Caravaque. 
 The restoration of  the Trinity Cathedral began after the foundation of the Museum on the territory of the Trinity-St. Sergius Lavra. It went on in the course of  several  decades. The Cathedral was cleared of  the rough subsequent structures: in 1925, the clumsy northern parvis was dismantled, in 1954, the external walls and the  dome were cleared of  canvas which was glued in the 18th century.  By 1966 the restoration determined and returned the most expressive view of the monument preserving the dome and the zakomars of the 16th century.  The clearance and restoration of the icons in the iconostasis began in 1918 and practically finished in the 1970s.
 
 
  St. Nikon Chapel  (1548)
  St. Sergius’s successor Nikon was buried at the southern wall of the Trinity Cathedral. In 1548, the so-called Nikon Chapel was constructed over his tomb. It is a church with one  cupola and one apse, without supporting pillar inside. The church is made of bricks. The walls are covered with white stone up to the top  of the apse. They are decorated with vertical semi-columns tight up with three rows of  beads. Constructing the Chapel close by the Trinity Cathedral, the craftsmen seemed to stress the spiritual contact between the Monastery founder and his disciple  and  successor.
