Plymouth has about 150 churches and its Roman Catholic cathedral (1858) is in Stonehouse. The city's oldest church is St Andrew's (Anglican) located at the top of Royal Parade—it is the largest parish church in Devon and has been a site of gathering since AD 800. The city also includes five Baptist churches, over twenty Methodist chapels, and thirteen Roman Catholic churches. In 1831 the first Brethren assembly in England, a movement of conservative non-denominational Evangelical Christians, was established in the city, so that Brethren are often called Plymouth Brethren, although the movement did not begin locally.
