Place Graslin, Pedestrian square in central Nantes, France.

Place Graslin is a pedestrian square in central Nantes formed by a rectangle joined to a south-facing hemicycle, with eight streets radiating from it. The Théâtre Graslin, a neoclassical building with eight Corinthian columns, twelve steps and a row of statues on the roofline, stands on the north side. A fountain occupies the center, and the Art Nouveau brasserie La Cigale faces the theater to the south.

From 1777, Jean-Joseph-Louis Graslin, receiver general of the king's farms, bought a sparsely populated rocky hill west of Nantes and launched a real-estate development. The city approved the name place Graslin on 22 September 1780. Architect Mathurin Crucy designed the ensemble, with the theatre dominating a semicircular square.

The Théâtre Graslin, completed in 1788 with eight Corinthian columns and statues of the Muses, has hosted opera and theatrical performances for over two centuries as a leading cultural venue.

Located at postal code 44000, the square is about 0.6 miles from Nantes railway station and connects to the city center via pedestrian streets Crébillon and Jean-Jacques Rousseau.

The square was among the first in Nantes to receive gas lighting in 1852, and its adjacent brasserie La Cigale has been recognized as one of France's most beautiful Art Nouveau restaurants.
