Nicéphore Niépce's House - Site of the first successful photograph

View from the Window at Le Gras (La cour du domaine du Gras) was the first successful permanent photograph, created by Nicéphore Niépce in 1826 at Saint-Loup-de-Varennes.


Nicéphore Niépce captured the photo with a camera obscura focused onto a sheet of 20 × 25 cm oil-treated bitumen. As a result of the 8-hour exposure, sunlight illuminates the buildings on both sides.
