Philippine Diamond Tower

The Philippine Diamond Tower was a proposed broadcast and observation tower intended to be a landmark in Quezon City, Philippines. Planned to reach a height of 612 meters, symbolizing the country's Independence Day, the tower was set to begin construction in 2015 and be completed by 2019. The project attracted interest from both Japanese and Chinese investors, with an estimated cost of ₱41.4 billion. Despite its ambitious vision to enhance the skyline of Manila and serve as a major tourist attraction, the tower was never built.
