Montmartre is a large hill in Paris's 18th arrondissement. It is 130 m (430 ft) high and gives its name to the surrounding district, part of the Right Bank in the northern section of the city. The historic district established by the City of Paris in 1995 is bordered by rue Caulaincourt and rue Custine on the north, rue de Clignancourt on the east, and boulevard de Clichy and boulevard de Rochechouart to the south, containing 60 ha (150 acres). Montmartre is primarily known for the white-domed Basilica of the Sacré-Cœur on its summit and as a nightclub district. The other, older, church on the hill is Saint Pierre de Montmartre, which claims to be the location at which the Jesuit order of priests was founded.
