# The Split palace becomes, in later centuries, the core of a living city rather than a sealed tomb

Date: 305

## The fact

[Diocletian](/people/diocletian)’s retirement palace at Spalatum was later occupied as the core of Split, a rare imperial residence that became a city rather than a ruin-only precinct. The dated modern instrument is that urban-continuity file.

It is one event.

## Context

Building labour is extractive. Later habitation is a cohesion path of medium confidence as his increment: he built walls people could reuse.

Diocletian’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

Built for retirement from 293–305. Later medieval Split inhabited the walls. UNESCO records that continuity. He did not plan a commune.
Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers date the row.

## Evidence and sources

UNESCO Split and the city/palace portals independently describe habitation inside the palace.

Official or archival record: UNESCO — Historical Complex of Split with the Palace of Diocletian (https://whc.unesco.org/en/list/97/; UNESCO World Heritage Centre).

## Significance

Reusable palace-walls as a city core are a limited urban-cohesion path.

A later commune is not a 303 edict.

Reusable palace-walls as a city core are a limited urban-cohesion path.

## What is established and what is not

Established: later Split inhabits the palace. Not established: that he designed a free city, or that building labour was free.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Diocletian.

What would change the picture: a contradictory original with a different date, signatory, or non-occurrence; a demonstrated forgery; or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of other causes.

They are not a public rating.
