1099–1291 · REGNUM HIEROSOLYMITANUM
People, places and symbols
behind a changing medieval kingdom.
A KINGDOM BEYOND ONE CITY
Jerusalem gave the kingdom its name. Ports, inland towns, religious communities and royal families made it more than one city. Explore the routes between its places and the people who shaped its story.
PLACES / CHANGING FRONTIERS
Follow the shift from Jerusalem to Acre. Choose a date to see the story change.
Jerusalem was the royal and spiritual centre, connected to coastal ports and inland strongholds. The kingdom’s reach extended beyond the city itself.
Jerusalem’s loss shifted the kingdom’s centre towards Acre. Diplomacy restored Christian rule in Jerusalem in 1229; the city was lost again in 1244.

Explore the official heritage page ↗East of the Dead Sea, Kerak’s castle dominates a high fortified town. Vaulted halls and passages reveal a stronghold that was also a place of residence, storage and administration. The surviving site contains layers beyond its crusader past.

PEOPLE / PILGRIMAGE / EXCHANGE
Jerusalem was sacred to Christians, Muslims and Jews. Pilgrimage connected it to distant communities; sacred buildings and objects carried meanings that changed with rulers and religious access.
Medieval Jerusalem’s art reflects many languages and cultural traditions. Looking at a manuscript, a metal vessel or a church furnishing reveals connections that a campaign map cannot show.
The history of the kingdom includes patients and travellers as well as rulers. Our Hospitals & Service page follows that thread through the Hospitallers and other communities.
