Nero's residence created after the fire of ad 64, and notorious for its novelties and extravagance. Nero was esp. castigated for turning a vast area of the centre of Rome into a regal park, with residential nuclei dispersed within landscaped gardens extending from the Palatine to the Oppian and Caelian hills around an artificial lake. The main entrance was from the Forum along the new via Sacra through a colonnaded vestibule housing a colossal bronze statue of Nero. New palatial buildings were added to existing imperial properties on the Palatine and Esquiline, the best preserved of which is the Oppian wing incorporated into the substructures of the baths of Trajan. The long colonnaded structure, developed on at least two levels with symmetrical five‐sided courts either side of a remarkable domed octagonal hall, borrows much from Hellenistic palaces and Roman villa architecture but uses vaulted concrete construction in an unprecedented fashion (see building materials).
