We know that the High Choir predates 1551, as it was mentioned in a report of that year when the remains of Manuel I were transferred to the Monastery. This space served many of the fundamental activities of the monks of the Hieronymites Order - prayer, singing and religious acts - until the Chapter Room was completed in the 19th century.
The rows of chairs, which occupy almost all of the High Choir, are "one of the most beautiful works bequeathed to us by the artistic carpentry of the Renaissance", according to Haupt. It was designed by Diogo de Torralva and executed by Diogo de Çarça in 1548-1550. The Hieronymite monks, who followed the rules of St. Augustine, spent seven hours a day here, every day.
Above the balustrade hangs a sculpture of 'Crucified Christ' resplendent in silver, which is the work of Philippe de Vries and Filipe Brias. The walls are adorned by a number of paintings representing the Apostles (ten only, as two paintings were lost in 1755) and a painting of St. Jerome and one of St. Augustine, all by an unknown artist.
The balcony, which collapsed in the earthquake of 1755, was later rebuilt in 1883.
