8. The UFO Houses of Taiwan (Sanzhi UFO Houses)

They included rounded shapes, vibrant colors, and a design that resembled spaceships and flying saucers.

Unfortunately, the project faced several problems, including financial issues and local superstitions related to feng shui. Many claimed the buildings were cursed or unlucky places. Furthermore, several fatal accidents occurred during construction, generating even more controversy and speculation. In the mid-1980s, the buildings were officially abandoned and, in 2010, demolished. Structural deterioration and a lack of investors for their restoration and revitalization are the main causes.
