In the spring of 1294, monastery's founders, don Orlando and fra Guittone d'Arezzo purchased land close by the city's second set of defensive walls along what is today via degli Alfani. The monastery's Registro Nuovo, compiled around 1402 and transcribed by George Bent (1993, p. 605), indicates the first monastic church was quite small, measuring 13 braccia long, 11 braccia wide, and 7 braccia high, with its high altar measuring 3 braccia. Using the conversion of 58.36 cm to the braccia, Guido Tigler (2022, p. 39) has calculated that the small building was about 7.6 x 6.42 m (approximately 525 sq. ft.) with an altar table 1.75 m (5.75 ft.) wide.
