Created in 1983, the Jardin du Port de l’Arsenal is a discreet and charming oasis nestled between Place de la Bastille and the Seine, on the eastern bank of the basin by the same name. Covering about 1.4 hectares and stretching over 544 meters, it follows the winding Canal Saint-Martin, which became a pleasure port in place of the old Charles V moat dug under Napoleon starting in 1805.

The garden unfolds in successive terraces, designed by landscape architect Philippe Mathieux and urban planner Serge Eyzat. From the entrance, a broad alley lined with maples and willows leads to a romantic pergola decorated with roses, clematis and honeysuckle in spring. A bronze statue of Diana by Henry Arnold (1920s–30s) punctuates the gravel paths, while lavender and blue flowering ceanothus add summer charm. Stone and wooden seating areas invite visitors to pause and enjoy the peaceful setting.

Further down, a safe play area for children welcomes families. The narrow yet long lawns facing the water encourage relaxing picnics, in sun or shade.

The Grand Bleu restaurant-terrace, housed in a glass structure with greenery, offers stunning views of the basin, boats, and the Jim-Morrison footbridge (formerly Mornay), linking Bastille to Faubourg Saint-Antoine. Accessible via Bastille metro (lines 1, 5, 8), Sully-Morland or Quai-de-la-Rapée, the garden is open 24/7 year-round, with occasional footbridge closures for maintenance.

The setting is characterized by a serene atmosphere, midway between urban life and a riverside retreat. Wanderers, families, readers, cruise enthusiasts and boaters mingle here. Its ideal audience: city dwellers seeking tranquility, curious tourists, families with young children, and botanical lovers. Anecdotally, the garden incorporates remnants of the old military arsenal, especially the terraces which follow the previous structure of medieval moats.

Practical info: drinking water points and toilets are available, but public Wi‑Fi is not. Leashed dogs allowed; partial wheelchair access via Bastille side. A perfect spot for reading, watching boats, enjoying terrace lunch, or simply daydreaming by the water.
