Orangery of Jardin Massey, Greenhouse building in Jardin Massey, Tarbes, France

The Orangery of Jardin Massey is a 19th-century glasshouse built to overwinter the garden's tender trees. Its main hall holds orange, lemon and pomegranate trees, palms and flowering shrubs set on shelves and stands, with tall windows along the facade letting in light.

Placide Massey, former head gardener at the Palace of Versailles, laid out the Jardin Massey and had this orangery built; the garden opened to the public in 1853. The building was designed to overwinter the orange and lemon trees that stood outdoors in the garden during the warm months. It is listed among the heritage buildings selected by the 2021 mission for endangered built heritage.

The orangery is tied to Placide Massey, the Tarbes-born gardener who directed the gardens of the Palace of Versailles before laying out this garden. Its plant collection, with orange and lemon trees among the species, follows the old practice of moving tender plants outdoors in warm months and back under cover before frost.

The orangery stands inside the Jardin Massey, a short walk from the garden's main entrance in the centre of Tarbes. Its single hall is entered at ground level, with a central path between the plant stands, so visitors can move through without steps. The building also serves as shelter when rain interrupts a walk through the garden.

The orangery is listed among the heritage buildings selected in 2021 by the mission to identify endangered built heritage. The garden itself was laid out by Placide Massey, who had been head gardener at the Palace of Versailles before retiring to his native Tarbes.
