San Giovanni in Laterano - Pipe organs

The Biagi organ in the Archbasilica of St. John Lateran stands in the north transept with 27 stops arranged across two manual keyboards and a pedalboard, all using mechanical key action. Its construction combines functional engineering with artistic design typical of late Renaissance organ building.

Master organ builder Luca Biagi constructed this instrument between 1597 and 1599, introducing technical innovations that raised standards in the craft. Over subsequent centuries, notable craftsmen including Giuseppe Testa, Ugo Annibale Traeri, and Celestino Testa restored and maintained it to preserve its sound.

The organ case, designed by architect Giacomo della Porta, sits on a elevated tribune with yellow marble Corinthian columns that make it a visual centerpiece of the church. Its presence reflects how music and the organ have held a central role in the spiritual life of this ancient basilica.

The organ is positioned in an accessible location in the north transept where visitors to the basilica can easily view it from the main church spaces. The best perspective is gained by entering the church and looking upward toward the elevated tribune where it sits.

The upper keyboard spans 59 notes and includes split accidentals, a feature reflecting specific harmonic techniques from the late 16th century period. This unusual arrangement allowed musicians to perform techniques impossible with standard keyboard layouts.
