To the side of the museum lies the Saint's tomb in a beautifully arched construction, which has recently been converted into a church, the Tomb Church. The Saint's body was transferred from the public cemetery, which lies behind the square, into caskets of different sizes and shapes. Many tests had been done in order to stop the causes of the sweat and blood secretion phenomenon. On August 7th, 1952, the corpse was laid in the current grave. An iron gate, with a glass pane, was built to separate the visitors from the coffin, which is laid on a cedar wood pedestal, which is also laid on an Italian marble pedestal. Believers stand or kneel before the tomb praying to God and asking the intercession of St Charbel. A visitor speaks out what he/she would never speak anywhere else because St Charbel has become a closer friend to man, and the great interceder to the almighty and loving God.

Downstairs, the Saint Museum contains the liturgical clothes which were put on Saint Charbel's corpse, in the many graves in which he was put after his death. They are ruined clothes because of the secretion of sweat and blood from the Saint's corpse. In the Museum, one can also find a great amount of letters coming from many countries worldwide. Other monastic habits and liturgical clothes and various utensils used by the Saint during his life are also displayed in the Museum. There are also ex-voto and other matters offered after miraculous healings and testifying the love of God for humanity through his chosen Saint.

After the beatification of St Charbel on December 5th, 1965, and with the incredibly increasing number of believers who came to Annaya, the monastery started the construction of a church, named after St Charbel, which can accommodate great multitudes of people. This church was built on the western side of the monastery. The church is round in shape. The altar is located in the center, a symbol of constant renewal of the world. It is located in such a way that those who come to pray can reach it from all directions to receive the Holy Communion, and to meet the living Christ Jesus, who renews them and changes their mortal sacrifices to eternal life. The upper parts of the entrances are of stained glass, depicting incidents and stages from St Charbel's life. This was implemented by the artist Saliba Douaihy, and was restored by Father Abdou Badawi.
