🌍 Dunn’s Castle, Piketberg: A Historic Swartland Stay Built Between 1892 and 1902

At the foot of the southern Piketberg Mountains, alongside the R399 between Piketberg and Velddrif, stands Dunn’s Castle: a stone-built historic residence with a Norman-style tower, Victorian-era interiors and a long connection to the town’s industrial history.

Piketberg itself developed around the former farm Grootfontein, granted to the Dutch Reformed Church in 1835; the first church was built there in 1836. The town was originally known as Piquetberg, with the spelling changing to Piketberg in the 1930s. It sits in the Swartland, an agricultural region known for wheat, vineyards, fruit farms and fynbos.

The man behind Dunn’s Castle

Dunn’s Castle was commissioned by George Herbert Dunn, who was born near Tavistock in Devon, England, on 14 June 1861. He arrived in Cape Town on 14 January 1882 and later acquired De Tuyn, a small farm at the foot of the Piquetberg Mountains.

According to the Piketberg Museum, Dunn envisioned a large residence on a plateau above the farm, originally with the idea of establishing a sanatorium. Construction began in 1892, was completed in 1902, and the property was registered in Dunn’s name in 1905.

The museum identifies C. J. Liebenberg as the builder. Dunn’s Castle was built in a U-shape and originally comprised 14 rooms, including a Norman-style tower.

Built from local stone and imported materials

The building’s construction tells its own story of late-19th-century logistics. Stone was collected from the surrounding area, moved by ox wagon, and cut and dressed on site. Cement and nails were imported from England. Twelve concrete-filled cement barrels still support the cellar beams.

The interior woodwork includes Oregon pine, kiaat and birch; the floors were made of birch and the roof beams of Norfolk pine. Roof tiles and hand washbasins were imported from France. The original house had seven guest bedrooms, each with its own fireplace. These details are recorded by the Piketberg Museum.

Dunn’s Castle is often linked to architect Sir Herbert Baker. However, the historical sources describe Baker’s role as an attribution rather than a confirmed fact: the museum says it is “thought” he was the architect, while the Vernacular Architecture Society of South Africa says the house is “believed” to be his work. The wide passages, tower and fireplaces are features associated with that attribution, but the architect should not be presented as conclusively confirmed. Piketberg Museum | VASSA research notes

From private residence to cement-company home

Dunn’s Castle became part of Piketberg’s industrial story in the 1920s. Cape Portland Cement bought the building in 1922 for construction workers and its general manager. Once worker housing had been completed in 1927, the castle became the general manager’s residence, a role it retained until 1988. It later passed through several owners and was used as a guesthouse.
