Belmont Castle was built c. 1795 for Zachariah Button, a wealthy local landowner, who also owned a neighbouring
chalk quarry. During the 1840s, when the property was occupied by the Webb family, it was the seat of local
cricket matches as well as a circle of music lovers mentioned by the pianist and writer
Alice Diehl in her memoirs. One of its later owners, Edward R. Parker, who lived at Belmont Castle from 1880 until 1900, was chairman of the board of governors Orsett of the Poor Law Union board of governors. During his time there, Belmont's park was often used for local events, including a political rally in support of the
Franchise Bill attended by 2000-3000 people in 1884. In the 20th century, the house was only sporadically occupied and chalk quarries increasingly encroached upon the pleasure grounds, although they were still used for charity fetes into the 1930s. When the Dobree family, the last tenants of the entire house, departed in 1930, the mansion was divided into individual rented flats and meeting rooms. The remaining land was let out to local farmers for grazing cattle and to the Tilbury Gas Company who used the North Lawn as a sports field and rented part of the mansion to use for changing rooms. The last owner of the property was the Associated Portland Cement Company, who had the mansion demolished in 1943 to make way for yet another chalk quarry. ==Architecture==
