The importance of Constantinople increased, but it was gradual. From the death of Constantine in 337 to the accession of Theodosius I, emperors had been resident only in the years 337–338, 347–351, 358–361, 368–369. Its status as a capital was recognized by the appointment of the first known Urban Prefect of the City Honoratus, who held office from 11 December 359 until 361. The urban prefects had concurrent jurisdiction over three provinces each in the adjacent dioceses of Thrace (in which the city was located), Pontus and Asia comparable to the 100-mile extraordinary jurisdiction of the prefect of Rome. The emperor Valens, who hated the city and spent only one year there, nevertheless built the Palace of Hebdomon on the shore of the Propontis near the Golden Gate, probably for use when reviewing troops. All the emperors up to Zeno and Basiliscus were crowned and acclaimed at the Hebdomon. Theodosius I founded the Church of John the Baptist to house the skull of the saint (today preserved at the Topkapı Palace), put up a memorial pillar to himself in the Forum of Taurus, and turned the ruined temple of Aphrodite into a coach house for the Praetorian Prefect; Arcadius built a new forum named after himself on the Mese, near the walls of Constantine.
