Between 1872-74 St Bartholomew's Church was built. In 1873 St. Peter's was made Brighton's parish church and in 1875 the Middle Street Synagogue opened. Nevertheless, Brighton has become known as one of the least religious places in the UK, based upon analysis of the 2001 census which revealed that 66,955 people (27 per cent of the population) professed no religion, almost double the national average of 15 per cent. Perhaps this is why 1870s secular buildings such as the The Aquarium (opened, 1872) and the museum and library (opened, 1874) continue to flourish.
