Parc du Thabor is a public garden located in the heart of Rennes, a city in the Brittany region of France. The park was designed in the 1860s by Denis and Eugène Bühler, landscape architects from Paris.

The park covers an area of 10 hectares and features a range of attractions including a large pond, a waterfall, a rose garden, and a children's playground. The park is also home to a botanical garden, which contains over 4,000 plant species from all over the world.

One of the most popular features of the park is the Orangery, a large glasshouse that was built in the late 19th century to house exotic plants. The Orangery is also used for temporary exhibitions and cultural events throughout the year.

Another notable feature of the park is the Thabor Chapel, which was built in the 19th century in the neo-Gothic style. The chapel is located on top of a hill in the park and provides panoramic views of the city.
