Castle Hall, Milford Haven, was built c.1765 for J. Z. Howell former governor of Bengal (survivor of the Black Hole of Calcutta). In 1804, Benjamin Rotch, North American Quaker and owner of whaling ships, who settled at Milford bought the Castle Hall estate. In the mid-19th century the estate was purchased by R.F Greville who had the house rebuilt in 1855-7. He added towers and a vast portico in Italian Renaissance style. The tower to the north of the house was some 27 metres (90 feet) high, with four niches mid way up in which were set over life-size statues. Between 1910-1917 the building was occupied by Benedictine nuns and known as St Brides Abbey. It was demolished in 1935.
