The Plan of Saint Gall is a medieval architectural drawing of a monastic compound dating from — AD. According to calculations based on the manuscript's tituli the complex was meant to house about monks , lay visitors, and craftmen and agricultural workers.
The Plan was never actually built. The planned church was intended to hold the relics of the monastery's founder and namesake, the hermit Saint Gall.

It is considered a national treasure of Switzerland and remains a significant object of interest among modern scholars, architects, artists and draftspeople for its uniqueness, its beauty, and the insights it provides into medieval culture.
