The park was created in the 19th century on the former site of the town's defensive ramparts, specifically the bastions of the medieval fortification system.
It is officially labeled as a 'Jardin Remarquable' (Remarkable Garden), a prestigious French national classification.
The garden contains a dedicated 'Jardin des Fossiles' (Fossil Garden) which utilizes natural limestone outcroppings.
The arboretum features several century-old trees that were planted during the initial landscape design in the mid-1800s.
The park provides a nesting habitat for several species of birds, including wood owls and various raptors.
The layout reflects the English landscape movement, characterized by curved paths and intentionally naturalistic groupings of plants.
The Jardin Public de Saint-Omer is a landscaped park designated as a 'Jardin Remarquable' by the French Ministry of Culture. Located on the site of former 17th-century fortifications, the park spans roughly 17 hectares and incorporates an English-style garden landscape. It features a fossil garden, a vast arboretum, and a significant collection of rare plant species. The park serves as a biological reservoir, hosting diverse avian populations and local wildlife. It is integrated with the remains of the old ramparts, allowing visitors to walk along historic defensive structures. The site also includes a bandstand and various botanical paths that navigate undulating terrain. The park is managed by the town of Saint-Omer and serves as a major green space for the city's inhabitants.

Wear comfortable walking shoes as the park features uneven, natural paths and slight inclines along the old fortifications.
Bring binoculars if you are interested in bird watching, as the dense arboretum area is a hotspot for local avian species.
Check the local city events calendar, as the bandstand occasionally hosts summer musical performances.
Do not attempt to climb the historic rampart walls, as they are fragile and pose a safety risk.
Stay on marked paths to protect the botanical collections and observe noise levels near residential borders.
