Throughout the 19th century, there
was an increase in the amount of purpose-built workers’ housing and,
by the mid-1820s, the urban area was based along Union Road. The
first school in Oswaldtwistle was opened in 1831. It was a Sunday
and day school, situated on New Lane on land donated by Robert
Peel. There was also a school located in some residential cottages
at Busk from 1837 until 1872, when a purpose built school was
erected on Union Road.
Although new housing was added to the area, it was not sufficient to
meet the demand. Crowded, unsanitary conditions lead to public
health issues with outbreaks of small pox, scarlet fever and typhoid
throughout the 1880s-90s. In 1892, the conditions were so poor that
600 houses stood vacant and Oswaldtwistle became known as the
“Deserted Village.
