This floor preparation of crushed tufo inside room 3 covers walls 5341, 5342, 5345, and 5346 and threshold 5344 and seems to be related to the construction phase of these walls. It may have served as the preparation layer for a cocciopesto floor similar to those in room 2 and room 1. Most likely this floor was part of a covered, indoor space.
