When the couple passed away, the 52-room house was used as a country club for a time. Then, a scientist couple leased the mansion and turned it into a museum while continuing to live there until their deaths. Nobody has lived in the house since 1988.

The mansion was built in 1819 to replace an early 17th-century house that burned down in 1810. In the 1970s, the house was used for mock medieval banquets, but it was further damaged by fire in the 1980s.
Cambusnethan House is on Scotland's Buildings at Risk Register at a "critical" risk level. A group called "Friends of Cambusnethan Priory" was established in 2014 to try to save the building from any further deterioration.

It cost an estimated $200 million to build in today's dollars. Although it's still in relatively good condition, it could cost up to $40 million to restore the hall and its grounds to their former glory, according to David B. Rowland, president of the Old York Road Historical Society.

Despite its state of disrepair, Lynnewood Hall is actually still worth millions — it's on the market for $15.5 million.

Pidhirtsi Castle in the Lviv region of Ukraine was built as a leisure home for a high-ranking Polish military commander between 1635 and 1640 by Italian architect Andrea dell'Aqua.

The mansion prospered for years, but in the 19th century, new owners took over and neglected the castle, so that by the end of World War II, it had massively deteriorated.

Pidhirtsi Castle has been damaged by fire and flooding over the years. The Lviv Art Gallery foundation aims to restore the mansion, but a lack of funds seems to have hampered progress. The foundation is calling for investors to help with the restoration while local students volunteer their time to try to repair the estate.

The Villa de Vecchi, known as the "Ghost Mansion" of Italy, was built between 1854 and 1857, meant to be the summer home of a Count named Felix De Vecchi, who was head of the Italian National Guard. The home had all the modern amenities of the time, including indoor heating pipes and a large pressurized fountain.

But it was home to a mysterious family tragedy. In 1862, the Count killed himself after he came home and found his wife murdered and his daughter missing. Relatives continued to live at the mansion until World War II, but the mansion was left uninhabited by the 1960s. The home's grand piano is said to be played at night by "a ghostly entity."

These ruins that resemble an ancient European castle actually sit just outside of Kansas City, Missouri, and are the results of a dream of businessman Robert Snyder, who wanted to build a European-style castle in Missouri.

Snyder started building in 1905, but the next year he was killed in a car accident and never saw it finished. His sons took over construction and lived there until the family ran out of money because of several lands rights lawsuits surrounding the castle’s property.
