1675. A large part of the estate was bought by Sir Samuel Astry of Henbury. The chapel's last ruins were removed in 1707. Blaise Castle House In the later 18th century, the estate was owned by a sugar merchant and investor in the slave trade, Thomas Farr, who bought it from Astry's descendants in 1762; he built the sham castle. Farr went bankrupt when ships he owned were blockaded during the American Revolutionary War, and the estate was bought in 1778 by Denham Skeate, a lawyer from Bath. Eleven years later he sold it to John Harford, a wealthy Bristol merchant and banker, who demolished the old house in 1789 and had the present two-storey Neoclassical Blaise Castle House built in 1796–1798, designed by William Paty. It is a square stone block with adjoining domestic offices which are faced with stucco. The north west entrance front has five bays with a central semicircular projecting porch with Ionic columns. It is a grade II* listed building, though described by Simon Jenkins as "solid, simple and unexciting". John Nash added a connected conservatory or orangery around 1805 or 1806, and in 1832–1833, Charles Robert Cockerell designed the Picture Room for Harford's son, John Scandrett Harford, who had inherited the estate after his father's death in 1812. The Picture Room extends into a portico which has six Ionic columns. This now houses a display of paintings from the Bristol City Museum and Art Gallery. The hall has bas-relief medallions by Bertel Thorvaldsen. The elder Harford also had Blaise Hamlet built to house his servants and tenants, to designs of Nash and George Repton, in 1811. The estate was sold to Bristol City Council in 1926, to preserve it from development. During World War II the house was occupied by the armed forces. A branch of the Bristol City Museum and Art Gallery since 1949, Blaise Castle House now features collections relating to household items in addition to its period interior decoration. Galleries have displays of historic domestic equipment used for lighting, cooking, cleaning, washing, including a display of toilets. Blaise Castle On a hill above the gorge is a sham castle in Gothic Revival style overlooking Bristol, Avonmouth and the Avon Gorge, with views across to South Wales on a clear day. It was built in 1766, by Robert Mylne, on the site of a chapel dedicated to Saint Blaise. The folly is
