After the fall of the Commune, Paris was governed under the strict surveillance of the conservative national government. The government and parliament did not return to the city from Versailles until 1879, although the Senate returned earlier to its seat in the Luxembourg Palace.[140] On 23 July 1873, the National Assembly endorsed the project of building a basilica at the site where the uprising of the Paris Commune had begun; it was intended to atone for the sufferings of Paris during the Franco-Prussian War and the Commune. The Basilica of Sacré-Cœur was built in a neo-Byzantine style and paid for by public subscription.
