About Larnach Castle
Larnach Castle is a mock castle standing along the Otago Peninsula's ridge, inside the Dunedin city limits in New Zealand, near the little settlement of Pukehiki. Few houses in the country match its scale. William Larnach, a prominent entrepreneur and politician, built it as his private residence. He simply called it "The Camp", and local press first dubbed it a "castle" on December 8, 1874, a few days after he and his wife Eliza moved in.
Land for the castle was bought in 1870, and Dunedin architect R.A. Lawson was chosen to design the Gothic Revival mansion. Construction began in 1871 once the site was cleared and leveled. About 200 workmen finished the main structure with materials from around the world, though much of the stone came from a nearby basalt quarry. Glass was imported from Venice in 1875. In 1887 a 3000-square-foot ballroom was finished, a gift for the 21st birthday of Larnach's eldest daughter, Kate. The complex eventually had 43 rooms and a staff of 46 servants.
In 1906 the family sold the house. Across the twentieth century it changed owners and uses constantly and fell into disrepair, until Barry and Margaret Barker bought it in 1967; the Barker family has since carried out significant restoration. It is open as a tourist attraction billed as "New Zealand's only castle", and its gardens are among only five in the country that the New Zealand Gardens Trust has rated "Garden of International Significance". Heritage New Zealand designated it a New Zealand Landmark in 2018, and it is reputed to be among the country's most haunted buildings.

- Towers and battlements
- The castle has several small towers and battlemented parapets. Print friendly adapts these small parts to the print scale; Full detail keeps them on a larger print with a fine nozzle.
- Small on a big hillside
- The castle is small compared with the hillside around it, so a larger print size keeps the towers readable. Layers of 0.12–0.16 mm help the fine detail.
- One piece with the ground
- Larnach Castle is joined to the ground in the exported file, and the four-side check found no floating parts, so nothing needs gluing.
