# The Baths of Trajan are dedicated on the Oppian as a public bathing complex

Date: 109

## The fact

In 109 the Baths of [Trajan](/people/trajan) were dedicated on the Oppian Hill as a public bathing and park complex. The dated building is not the Aqua Traiana dedication and not the Forum of Trajan. Trajan’s documented role is: He dedicated a vast bath complex over Nero’s Domus Aurea platform. Apollodorus is associated as architect; unnamed labour built; the emperor did not stoke the furnaces. Do not twin this with the Aqua Traiana. Water supply and a bath complex are different instruments. Later editors, printers, and excavators remain named where they appear. Trajan's documented role is: He dedicated a vast bath complex over Nero’s Domus Aurea platform. Apollodorus is associated as architect; unnamed labour built; the emperor did not stoke the furnaces.

## Context

Nero’s Golden House platform, Apollodorus’s architectural reputation, and a Fasti Ostienses type date share the file. Public baths are not a unique modern hospital.

The public setting is the file around 0109-06-22. Unnamed clerks, soldiers, printers, or later editors may appear without becoming this instrument. The instrument stays The Baths of Trajan are dedicated on the Oppian as a public bathing complex. The setting of The Baths of Trajan are dedicated on the Oppian as a public bathing complex is the public file around 0109-06-22. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver health-system-capacity is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
