Rambouillet lies on the edge of the vast Forest of Rambouillet (Forêt de Rambouillet or Forêt de l'Yveline), and is famous for its historical castle, the Château de Rambouillet, which hosted several international summits. Due to its proximity to Paris and Versailles, Rambouillet has long been an occasional seat of government.
The Palais du Roi de Rome. In 1784, on a parcel adjacent to the gardens of the castle, Louis XVI had ordered the construction of the Hôtel du Gouvernement, which was restored during the reign of Napoléon I, and renamed Palais du Roi de Rome as the official Rambouillet residence of Napoleon 's infant son. Its entrance is situated in the rue Charles de Gaulle, Rambouillet's main street.
The Hôtel de Ville, the former Bailliage (Bailiwicks building) was built in 1786 at the request of Louis XVI by the architect Jean-Jacques Thévenin. It was given by Emperor Napoléon I to the inhabitants of Rambouillet to serve as their City Hall. The inscription over the doors of the City Hall reads "Donated to the inhabitants of Rambouillet by Napoleon the Great, [in the] Year 1809".
The new Saint-Lubin church was built between 1868 and 1871. Its architect was Anatole de Baudot.
The Laiterie de la Reine, the Queen's Dairy also built on the grounds of the Domain of Rambouillet, is adjacent to the Bergerie. It was built in 1787 at the request of Louis XVI for his wife Marie Antoinette and designed by the architect Jean-Jacques Thévenin.
The Chaumière des coquillages, a thatched-roof cottage with its marble interior decorated with shells and mother of pearl, was built in 1779-1780 in the English garden of the Domain of Rambouillet by Claude-Martin Goupy, the architect of the duc de Penthièvre, for the princesse de Lamballe, Penthièvre's widowed daughter-in-law.
The Musée Rambolitrain, situated across from the Saint-Lubin church, is a museum featuring miniature trains. We find the a faithful reconstruction of a Parisian toy store of the 1930s.
The Monument Américain (The American Eagle Monument), is situated at the south entrance of the town on the D 906 road to Chartres, at the site of two ambushes in which seven American soldiers were killed, on 16 August 1944. The monument was erected in 1947. It bears the inscription: "À la mémoire des soldats américains tombés pour la libération de notre région en août 1944", "In memory of the American soldiers fallen for the liberation of our region in August 1944". The names of nine American soldiers are inscribed on a plaque on the monument. Commemorative ceremonies are held at the monument every 19 August.
