Parc de Bourran, Historical park in Mérignac, France.

Parc de Bourran is an 18-hectare park in Mérignac, laid out in 1890 by landscape architect Louis Le Breton around a large pond fed by the Devèze. The river is crossed by a romantic bridge built as a false ruin, and an artificial waterfall feeds the water. Twenty-four tree species, many from North America, are labelled with their common and scientific names, and the lawns carry flower beds.

The estate belonged to the Bourran family of Bordeaux parliamentarians in the 17th century, then to marquis de Cazeaux in the 18th. In 1768 it passed to François-Armand de Saige, Bordeaux mayor in 1791, guillotined in 1793. Ship-owner Émile Ravesies and banker Léopold Piganeau bought it in 1865, demolished the 18th-century chartreuse in 1869 and built the present château by Jules and Paul Lafargue. In 1890 they commissioned Orléans landscape architect Louis Le Breton to design the park.

The park functions as a place for nature observation and environmental education, with marked paths helping visitors discover different tree species and plants. Local people come here to spend time outdoors and learn about sustainable practices such as traditional fruit tree cultivation.

The park is open daily with varying closing times by season, from 6:30 PM in winter to 9 PM in summer. It helps to visit in the morning or early afternoon to enjoy quieter times and explore the different areas at a leisurely pace.

In 1775 François-Armand de Saige had an ice house built at Bourran, described at the time as the largest in France. Its vaulted cellars were cut up to ten metres deep into the limestone and filled with ice from the frozen waters of the Devèze in winter or brought from the Pyrenees, to chill the fruit sorbets served in Bordeaux's wealthy households.
