I do have a project that's been running about 25-years. But it's not static - new features are added, bugs are fixed, and it just keeps going. Some of the code and the overall architecture are original but there's plenty of new.

That said though, the vast majority of projects I've been on are probably no longer in existence. This is why I take a more casual approach to most projects - I see it as somewhat temporary and it doesn't make sense to put so much effort into a clean project.
