The parish of Winslade contains a total of 42
listed buildings—the majority of which are located in Hackwood Park—including three Grade II* listed. Hackwood House is an imposing mansion of symmetrical design, with the original structure dating from 1680. The exterior has four
Neo-classical columns, which are situated in front of pilasters raised from the main wall surface. The central doorway is housed in an oval recess and also contains two columns and pilasters at the side. The interior of Hackwood House contains panelling and a large fireplace of late 17th century style, with a carved ornamental
festoon brought from Abbotstone House in Wiltshire. Other listed buildings in Hackwood Park are the fishing temple, a once-domed building with eight columns and an incomplete circular stone base, a 19th-century teahouse pavilion, a single story mid-18th century orangey, a statue of
George I which dates from 1722, and a late 19th-century mill house. Grade II* listed buildings include an early 19th-century stable block and riding school, and a menagerie pond pavilion, which dates from 1727 and was given as a gift by James Gibbs to the third Duke of Bolton. The church of St Mary is a plain rectangular plan with a yellow brick tower and slate roofing. Although the site is old, the present church dates from 1816 and was Grade II listed on 26 April 1957. The church is described as a "rather unattractive building" with plastered walls, weathered stone bands and slender openings. Another place of worship was the Winslade Congregational Chapel, which is situated near a footpath leading to the villages of
Herriard and
Ellisfield. The chapel was opened in October 1888 by the fifth
Earl of Portsmouth and Thomas Maton Kingdon, an ironmonger from Basingstoke. The deacons of London Street in Basingstoke decided to close it in 1930 and was eventually sold to the Portsmouth Estate five years later for £35 (). ==References==
