 The closure was prevented due to a public campaign led by Charles Robert Ashbee, who set up a "Committee for the Survey of the Memorials of Greater London".The almshouses were the first buildings to be put on his preservation register, which eventually became the listed building system.In 1927, a bronze bust memorial for William Booth was installed at Trinity Green; in the 19th century, Booth had preached in the Vine Tavern in front of the almshouses, which had led to the founding of The Salvation Army.
