Explore Orsay through its architectural history, contemporary art and varied trails. The Église Saint-Martin-Saint-Laurent was founded in 1151; at the same time, the GR 655 – Ouest runs through Orsay on its route from Paris to Tours. There is also a promenade along the Yvette, a botanical garden and a walk by Lac du Mail. This gives you a choice of different ways to spend your stay, with varying time and practical requirements for individual visits.
Architectural history and cultural sites
The Église Saint-Martin-Saint-Laurent has a choir and a bell tower. The bell tower is Gothic and the oldest part of the church. The founding date of 1151 and the age of this building element offer two different points of reference if you are interested in the town’s architecture.
The Temple de la Gloire was built in 1801 and was partially protected as a Monument historique on 27 September 1979. These dates mark different milestones: the temple’s construction and its later protected status. Beneath the funerary chapel of the Église Saint-Martin-Saint-Laurent lies the Crypte d’Orsay, an exhibition space for contemporary art. In this way, ecclesiastical architectural history, a historic temple and a space for contemporary art offer distinct cultural themes side by side.
Trails and walks
The Way of St James is marked here as the long-distance hiking trail GR 655 – Ouest. On its route from Paris to Tours, it passes through Orsay and by Lac du Mail. Another point of reference is the Promenade Lecomte de Lisle: it runs along the Yvette and connects Orsay with Palaiseau through green surroundings. This comparison can help you choose the focus of your walk: the GR is part of a longer route, while the promenade links the two towns along the river.
Lac du Mail is a pleasant place for a waterside walk. The GR 655 – Ouest also passes by the lake, making Lac du Mail a shared point of reference for the long-distance trail and the lakeside walk. By contrast, the Promenade Lecomte de Lisle is defined by the Yvette and its connection between Orsay and Palaiseau. These different routes give you a concrete choice, as the walks do not all follow the same course.
Botanical garden and planning your visit
The Jardin Botanique de Launay – Université Paris-Saclay received the “Jardin botanique de France et des pays francophones” designation in 2001. Its collections comprise around 3,000 taxa. The designation and the approximate number of taxa describe different aspects of the garden: its recognition and the extent of its collections.
Visiting conditions are important when choosing when to travel. The Temple de la Gloire is privately owned and can be visited in summer; check the dates before you travel. The botanical garden is open daily throughout the year. As access arrangements may change, check the information before your visit. The archaeological site of the Villa Gallo-Romaine de Moulon is also open to the public; check the condition of the site before you travel.
If you are looking for a hotel in Orsay, you can start planning your stay around the topics that interest you most: architectural history, contemporary art, botanical collections or waterside trails. Bear your travel dates in mind if you would like to visit the privately owned Temple de la Gloire. For the garden and archaeological site, up-to-date access information can help you plan your visit.
