Hospitaller commandery of Saint-Jean-d'Acre

The Hospitaller commandery of Saint-Jean-d'Acre is a medieval fortification in Acre, Israel. The structure centers on a large courtyard surrounded by arcades, with deep wells and shallow pools for water storage, while the north wing contains vaulted rooms enclosed by thick exterior walls.

The Knights Hospitaller operated this fortress as their headquarters from 1149 until 1291, when the city fell to Muslim forces. This long occupation shaped the building's design and military function during the Crusade era.

The southern wing displays architectural elements bearing French royal symbols that reflect the building's role during the Crusade era. These details show how European nobility expressed their power through construction and design.

Visitors should wear sturdy shoes for uneven floors and stairs, as the site includes tunnels and multiple levels to explore. The vaulted rooms tend to stay cool, so bringing a light jacket is advisable.

An intricate network of underground tunnels connects different sections of the fortress, with archaeological evidence of medieval sugar production within the complex. These hidden passages reveal that the site served both military and industrial purposes.
