During the 20th century, a number of small factories were established in the area. The largest was Tilley Lamps Ltd (1915 to 1961), which employed around 300 people and manufactured pressure paraffin lamps (rather charmingly called "Aladdin" lamps in the 1930s). In December 1969, planning permission was granted for the development of a new shopping precinct on Brent Street to be called Sentinel Square, at a cost of £1.5 million, and within a year the old "Rose and Crown" pub, the Classic Cinema (once called the Gala), and a number of shops had been replaced with a collection of modernist shops and a Tesco supermarket. The Odeon at the Quadrant was opened in 1939 at what had been Cook's Corner in Parson Street. It was pulled down in 1979 and the site redeveloped for housing.
