“…Building 5 lies immediately to the south of the excavated part of the Palazzo Imperiale , and formed part of the same original architectural concept. Fieldwork undertaken in 2011 and 2012 (Keay et al , 2012) revealed that it was a vast, single building measuring 240 × 58 m, organized into a series of regularly spaced parallel spaces oriented from north to south. Each of these was in turn subdivided in a consistent sequence: a passage 4 m wide, three narrow bays each c. 11 m wide, a passage 4 m wide, and a wide bay c. 19 m wide.…”
